Organization and Basis of Presentation [Abstract]
ORGANIZATION AND BASIS OF PRESENTATION	Note 1 – Organization and Basis of Presentation *Organization and Principal Business Activities* Nxt-ID, Inc. (“Nxt-ID” or the “Company”) was incorporated in the State of Delaware on February 8, 2012. Nxt-ID is a security technology company and operates its business in one segment – hardware and software security systems and applications. The Company evaluates the performance of its business on, among other things, profit and loss from operations. The Company’s innovative MobileBio solution mitigates risks associated with mobile computing, m-commerce and smart OS-enabled devices. With extensive experience in biometric identity verification, security, privacy, encryption and data protection, payments, miniaturization and sensor technologies, the Company partners with companies to provide solutions for modern payment and the “Internet of Things” (“IoT”) applications. On July 25, 2016, the Company completed the acquisition of LogicMark, LLC (“LogicMark”) pursuant to an Interest Purchase Agreement by and among the Company, LogicMark and the holders of all of the membership interests of LogicMark (the “LogicMark Sellers”), dated May 17, 2016 (the “Interest Purchase Agreement”). Pursuant to the Interest Purchase Agreement, we acquired all of the membership interests of LogicMark from the LogicMark Sellers for (i) $17.5 million in cash consideration (ii) $2.5 million in a secured promissory note (the “LogicMark Note”) issued to LogicMark Investment Partners, LLC, as representative of the LogicMark Sellers (the “LogicMark Representative”) (iii) 78,740 shares of common stock, which were issued upon signing of the Interest Purchase Agreement (the “LogicMark Shares”), and (iv) warrants (the “LogicMark Warrants”) to purchase an aggregate of 157,480 shares of common stock (the “LogicMark Warrant Shares”) for no additional consideration. Such warrants were exercised on July 27, 2016. In addition, the Company was required to pay the LogicMark Sellers earn-out payments of (i) up to $1,500,000 for calendar year 2016 and (ii) up to $5,000,000 for calendar year 2017 if LogicMark met certain gross profit targets set forth in the Interest Purchase Agreement. The LogicMark Note originally was to mature on September 23, 2016 but was extended to July 15, 2017. The earn-out payment related to 2016 and the remaining balance owed on the LogicMark Note including accrued interest were both paid in July 2017. See Notes 5 and 7. Based on LogicMark’s operating results for the year ended December 31, 2017, the 2017 earnout amount owed by the Company is $3,156,088. As a result, the Company reduced the amount of contingent consideration due to the LogicMark Sellers by $1,843,912. The Company intends to pay the 2017 earnout amount of $3,156,088 to the LogicMark Sellers in the second quarter of 2018. See Note 8. On May 23, 2017, the Company completed a merger (the “Merger”) pursuant to an executed Agreement and Plan of Merger (the “Merger Agreement”) by and among the Company, Fit Merger Sub, Inc., a wholly-owned subsidiary of the Company (the “Merger Sub”), Fit Pay, Inc. (“Fit Pay”), Michael Orlando (“Orlando”), Giesecke & Devrient Mobile Security America, Inc. (“G&D”), the other stockholders of Fit Pay (the “Other Holders”) and Michael Orlando. See Note 4. The Company’s wholly-owned subsidiary, LogicMark, manufactures and distributes non-monitored and monitored personal emergency response systems sold through the United States Department of Veterans Affairs, healthcare durable medical equipment dealers and distributors and monitored security dealers and distributors. The Company’s wholly-owned subsidiary, Fit Pay has a proprietary technology platform that delivers payment, credential management, authentication and other secure services to the IoT ecosystem. The platform uses tokenization, a payment security technology that replaces cardholders’ account information with a unique digital identifier, to transact highly secure contactless payment and authentication services. *Basis of Presentation* The accompanying unaudited condensed consolidated financial statements as of March 31, 2018, and for the three months ended March 31, 2018 and 2017 have been prepared in accordance with the accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and pursuant to the instructions to Form 10-Q and Article 8 of Regulation S-X of the Securities and Exchange Commission (“SEC”) and on the same basis as the Company prepares its annual audited consolidated financial statements. The unaudited condensed consolidated balance sheet as of March 31, 2018 and the condensed consolidated statements of operations and cash flows for the three months ended March 31, 2018 and March 31, 2017 are unaudited, but include all adjustments, consisting only of normal recurring adjustments, which the Company considers necessary for a fair presentation of the financial position, operating results and cash flows for the periods presented. The results for the three months ended March 31, 2018 are not necessarily indicative of results to be expected for the year ending December 31, 2018, or for any future interim period. The condensed consolidated balance sheet at December 31, 2017 has been derived from audited consolidated financial statements. However, it does not include all of the information and notes required by U.S. GAAP for complete consolidated financial statements. The accompanying condensed consolidated financial statements should be read in conjunction with the consolidated financial statements for the year ended December 31, 2017, and notes thereto included in the Company’s annual report on Form 10-K, which was filed with the SEC on April 2, 2018.

Summary of Significant Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	Note 3 – Summary Of Significant Accounting Policies *Use of estimates in the financial statements* The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. The Company’s management evaluates these significant estimates and assumptions included those related to the fair value of acquired assets and liabilities, stock based compensation, derivative instruments, income taxes, accounts receivable and inventories, and other matters that affect the condensed consolidated financial statements and disclosures. Actual results could differ from those estimates. *Principles of consolidation* The condensed consolidated financial statements include the accounts of Nxt-ID and its wholly-owned subsidiaries, 3D-ID, LogicMark and Fit Pay. Intercompany balances and transactions have been eliminated in consolidation. *Concentrations of Credit Risk* The Company is a party to a Master Development Agreement with World Ventures Holding, LLC (“WVH”), a related party. WVH is considered a related party since the Chief Technology Officer of WVH is a director of Nxt-ID, Inc. During the three months ended March 31, 2018 and 2017, the Company recognized revenue of $254,258 and $2,708,036, respectively from WVH. At March 31, 2018 and December 31, 2017, the Company’s accounts receivable, net balance included $995,787 and $1,364,405, respectively due from WVH. *Revenue Recognition* The Company primary source of revenues is from product sales to its customers. The Company recognizes revenue when persuasive evidence of an arrangement exists, the service has been rendered or product delivery has occurred, the price is fixed or readily determinable and collectability of the sale is reasonably assured. The Company’s revenue is recorded at the net amount to be received after deductions for discounts, allowances and product returns. *Accounts Receivable* Accounts receivable is stated at net realizable value. The Company regularly reviews accounts receivable balances and adjusts the receivable reserves as necessary whenever events or circumstances indicate the carrying value may not be recoverable. At March 31, 2018 and December 31, 2017, the Company had an allowance for doubtful accounts of $402,383. *Inventory* The Company performs regular reviews of inventory quantities on hand and evaluates the realizable value of its inventories. The Company adjusts the carrying value of the inventory as necessary with estimated valuation reserves for excess, obsolete, and slow-moving inventory by comparing the individual inventory parts to forecasted product demand or production requirements. As of March 31, 2018 inventory was comprised of $1,588,842 in raw materials and $1,408,128 in finished goods on hand. Inventory at December 31, 2017 was comprised of $1,493,995 in raw materials and $1,565,522 in finished goods on hand. The Company is required to prepay for raw materials with certain vendors until credit terms can be established. As of March 31, 2018, and December 31, 2017, the Company had prepaid inventory of $910,568 and $887,021, respectively. These prepayments were made primarily for raw materials inventory and prepaid inventory is included in prepaid expenses and other current assets on the condensed consolidated balance sheet. *Goodwill* The Company’s goodwill relates to the acquisitions of LogicMark and Fit Pay. The Company began testing goodwill for impairment in the third quarter of 2017 as it relates to the acquisition of LogicMark. The Company will begin testing the Fit Pay related goodwill for impairment annually in the second quarter of 2018. Authoritative accounting guidance allows the Company to first assess qualitative factors to determine whether it is necessary to perform the more detailed two-step quantitative goodwill impairment test. The Company performs the quantitative test if its qualitative assessment determined it is more likely than not that a reporting unit’s fair value is less than its carrying amount. The Company may elect to bypass the qualitative assessment and proceed directly to the quantitative test for any reporting units or assets. The quantitative goodwill impairment test, if necessary, is a two-step process. The first step is to identify the existence of a potential impairment by comparing the fair value of a reporting unit (the estimated fair value of a reporting unit is calculated using a discounted cash flow model) with its carrying amount, including goodwill. If the fair value of a reporting unit exceeds its carrying amount, the reporting unit’s goodwill is considered not to be impaired and performance of the second step of the quantitative goodwill impairment test is unnecessary. However, if the carrying amount of a reporting unit exceeds its fair value, the second step of the quantitative goodwill impairment test is performed to measure the amount of impairment loss to be recorded, if any. The second step of the quantitative goodwill impairment test compares the implied fair value of the reporting unit’s goodwill with the carrying amount of that goodwill. If the carrying amount of the reporting unit’s goodwill exceeds its implied fair value, an impairment loss is recognized in an amount equal to that excess. The implied fair value of goodwill is determined using the same approach as employed when determining the amount of goodwill that would be recognized in a business combination. That is, the fair value of the reporting unit is allocated to all of its assets and liabilities as if the reporting unit had been acquired in a business combination and the fair value was the purchase price paid to acquire the reporting unit. As part of the annual evaluation of the LogicMark related goodwill, the Company utilized the option to first assess qualitative factors, which include but are not limited to, economic, market and industry conditions, as well as the financial performance of LogicMark. In accordance with applicable guidance, an entity is not required to calculate the fair value of a reporting unit if, after assessing these qualitative factors, the Company determines that it is more likely than not that its reporting unit’s fair value is greater than its carrying amount. During the year ended December 31, 2017, the Company determined that it was more likely than not that the fair value of LogicMark exceeded its respective carrying amount and therefore, a quantitative assessment was not required. As of March 31, 2018, there were no triggering events which would have necessitated an interim period evaluation. *Other Intangible Assets* The Company’s intangible assets are all related to the acquisitions of Fit Pay and LogicMark and are included in other intangible assets in the Company’s condensed consolidated balance sheets at March 31, 2018, and December 31, 2017. At March 31, 2018, the other intangible assets relating to the acquisition of LogicMark are comprised of patents of $3,471,980; trademarks of $1,151,618; and customer relationships of $2,712,464. At December 31, 2017, the other intangible assets are comprised of patents of $3,563,885; trademarks of $1,167,122; and customer relationships of $2,792,900. The Company will continue amortizing these intangible assets using the straight line method over their estimated useful lives which for the patents, trademarks and customer relationships are 11 years; 20 years; and 10 years, respectively. During the three months ended March 31, 2018 and 2017, the Company had amortization expense of $187,845 related to the LogicMark intangible assets. At March 31, 2018, the other intangible assets relating to the acquisition of Fit Pay, which was completed on May 23, 2017, are comprised of trademarks of $157,414; technology of $2,193,737; and customer relationships of $1,240,534. At December 31, 2017, the other intangible assets are comprised of trademarks of $181,042; technology of $2,284,739; and customer relationships of $1,336,868. The Company will continue amortizing these intangible assets using the straight-line method over their estimated useful lives which for the patents, trademarks and customer relationships are 5 years; 7 years; and 6 years, respectively. During the three months ended March 31, 2018, the Company had amortization expense of $210,964 related to the Fit Pay intangible assets. As of March 31, 2018, total amortization expense estimated for the remainder of fiscal 2018 is approximately $998,000 and for each of the next five fiscal years, 2019 through 2023 the total amortization expense is estimated to be as follows: 2019 - $1,400,000; 2020 - $1,400,000; 2021 - $1,400,000; 2022 - $1,388,000; 2023 - $1,248,000. *Stock-Based Compensation* The Company accounts for share-based awards exchanged for employee services at the estimated grant date fair value of the award. The Company accounts for equity instruments issued to non-employees at their fair value on the measurement date. The measurement of stock-based compensation is subject to periodic adjustment as the underlying equity instrument vests or becomes non-forfeitable. Non-employee stock-based compensation charges are amortized over the vesting period or as earned. Stock-based compensation is recorded in the same component of operating expenses as if it were paid in cash. The Company generally issues new shares of common stock to satisfy conversion and warrant exercises. *Net Loss per Share* Basic loss per share was computed using the weighted average number of common shares outstanding. Diluted loss per share includes the effect of diluted common stock equivalents. Potentially dilutive securities from the exercise of 4,602,650 warrants as of March 31, 2018 were excluded from the computation of diluted net loss per share because the effect of their inclusion would have been anti-dilutive. As of March 31, 2017, potentially dilutive securities of 1,749,805 realizable from the Series A Preferred Stock and Series B Preferred Stock, 575,000 from the convertible exchange notes and from the exercise of 1,829,049 warrants were excluded from the computation of diluted net loss per share because the effect of their inclusion would have been anti-dilutive. *Recent Accounting Pronouncements* In May 2017, the Financial Accounting Standards Board (the “FASB”) issued ASU 2017-09, “Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting” to provide clarity and reduce both (1) diversity in practice and (2) cost and complexity when applying the guidance in Topic 718, Compensation—Stock Compensation, to a change to the terms or conditions of a share-based payment award. The amendments in this Update provide guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. The amendments in this Update are effective for all entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. Early adoption is permitted. This ASU was adopted and it did not have a material impact on the Company’s condensed consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-01, “Business Combinations (Topic 805): Clarifying the Definition of a Business.” The amendments in this update clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of businesses. The amendments in this update provide a screen to determine when a set is not a business. If the screen is not met, it (1) requires that to be considered a business, a set must include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create output and (2) removes the evaluation of whether a market participant could replace the missing elements. The amendments in this Update are effective for all entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. This ASU was adopted and it did not have a material impact on the Company’s condensed consolidated financial statements. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows: Restricted Cash (“ASU No. 2016-18”). The amendments address diversity in practice that exists in the classification and presentation of changes in restricted cash and require that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. This ASU is effective retrospectively for fiscal years and interim periods within those years beginning after December 15, 2017. As permitted under the standard for emerging growth companies, the Company plans to adopt ASU 2016-18 in the first quarter of 2019. The Company is currently reviewing and evaluating this guidance and its impact on its condensed consolidated financial statements. In May 2016, the FASB issued ASU No. 2016-12 (“ASU 2016-12”), “Revenue from Contracts with Customers (Topic 606): Narrow- Scope Improvements and Practical Expedients.” ASU 2016-12 will affect all entities that enter into contracts with customers to transfer goods or services (that are an output of the entity’s ordinary activities) in exchange for consideration. The amendments in this update affect the guidance in ASU 2014-09 which is not yet effective, the amendments in this update affect narrow aspects of Topic 606 including among others: assessing collectability criterion, noncash consideration, and presentation of sales taxes and other similar taxes collected from customers. The effective date and transition requirements for the amendments in this update are the same as the effective date and transition requirements for ASU 2014-09. The Company is currently evaluating the effect that ASU 2016-12 will have on the Company’s financial position and results of operations. In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers ("ASU 2014-09"), which stipulates that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for such goods or services. To achieve this core principle, an entity should apply the following steps: (1) identify the contract(s) with a customer; (2) identify the performance obligations in the contract(s); (3) determine the transaction price(s); (4) allocate the transaction price(s) to the performance obligations in the contract(s); and (5) recognize revenue when (or as) the entity satisfies a performance obligation. The guidance also requires advanced disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from an entity's contracts with customers. In August 2015, the FASB issued Accounting Standards Update No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date ("ASU 2015-14"), which defers the effective date of FASB's revenue standard under ASU 2014-09 by one year for all entities and permits early adoption on a limited basis. As a result of ASU 2015-14, the guidance under ASU 2014-09 shall apply for annual reporting periods beginning after December 15, 2017, including interim reporting periods within that period. Early adoption is permitted as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within those annual periods. In March 2016, the FASB issued Accounting Standards Update No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net), which clarified the implementation guidance on principal versus agent considerations. In April 2016, the FASB issued Accounting Standards Update No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing, which clarified the implementation guidance regarding performance obligations and licensing arrangements. As permitted under the standard for emerging growth companies, the Company plans to adopt ASU 2014-09 in the first quarter of 2019 using the modified retrospective approach and recognize the cumulative effect to existing contracts in opening retained earnings on the effective date. The Company is currently reviewing and evaluating this guidance and its impact on its condensed consolidated financial statements. Therefore, the Company’s results may not be comparable with others companies in our industry until ASU 2014-09 is adopted.

Acquisitions [Abstract]

ACQUISITIONS

Note 4 – Acquisitions

Acquisition of logicmark llc

On July 25, 2016, the Company completed the acquisition of LogicMark. The Company determined that as of July 25, 2016, it was more likely than not that these gross profit targets as it relates to the contingent considerations would be achieved and any fair value adjustment of the earnout was due to time value of the payout. Based on LogicMark’s operating results for the year ended December 31, 2017, the Company reduced the amount of contingent consideration due to the LogicMark Sellers by $1,843,912. As a result, the Company intends to pay the 2017 earnout amount of $3,156,088 to the LogicMark Sellers in the second quarter of 2018. See Note 8.

On July 25, 2016, and in order to fund part of the proceeds of the LogicMark acquisition, the Company and a group of lenders, including ExWorks Capital Fund I, L.P. as agent for the lenders (collectively, the “Lenders”), entered into a Loan and Security Agreement (the “Loan Agreement”), whereby the Lenders extended a revolving loan (the “Revolving Loan”) to the Company in the principal amount of $15,000,000 (the “Debt Financing”). During the year ended December 31, 2017, the Company paid down $3,000,000 of the revolving loan. The Company originally incurred $1,357,356 in deferred debt issue costs related to the revolving loan. In addition, the Company incurred an additional $450,000 in deferred debt issue costs as a result of extending the revolving loan facility for one additional year. At March 31, 2018 and December 31, 2017 the unamortized balance of deferred debt issue costs was $112,613 and $200,744, respectively. The maturity date of the Revolving Loan is July 25, 2018, and the Revolving Loan bears interest at a rate of 15% per annum.

The Loan Agreement contains customary covenants, including an EBITDA requirement and a fixed change ratio, as defined in the agreement. As of March 31, 2018, the Company was in compliance with such covenants.

The Company has the ability to extend the Revolver for one additional year at its sole discretion with no subjective acceleration by the lender, provided the Company is not in default on the loan. The Company intends to exercise the option to extend the maturity date by one year and accordingly, the Company has classified the Revolver as a non-current liability as of March 31, 2018 and December 31, 2017.

Acquisition of Fit Pay

As discussed in Note 1, the Company completed the Merger on May 23, 2017. Pursuant to the terms of the Merger Agreement, the aggregate purchase price paid for Fit Pay stock was: (i) 1,912,303 shares of common stock which was equivalent to 19.96% of the outstanding shares of common stock of the Company (the “Common Stock”); (ii) 2,000 shares of the Series C Non-Convertible Preferred Stock of the Company (the “Series C Preferred Stock”); (iii) the payment of certain debts by the Company; and (iv) the payment of certain unpaid expenses of the Fit Pay Sellers of $724,116 by the Company. In addition, the Company will be required to pay the Fit Pay Sellers an earn-out payment equal to 12.5% of the gross revenue derived from Fit Pay’s technology for sixteen (16) fiscal quarters commencing on October 1, 2017 and ending on December 31, 2021. To date, Fit Pay has had minimal revenue. The operating results of Fit Pay have been included in the condensed consolidated financial statements from the effective date of the acquisition, May 23, 2017.

In connection with the Merger on May 23, 2017, the Company recorded deferred tax liabilities of $1,774,539 as part of its purchase price allocation.

Allocation of Purchase Price of Fit Pay

The purchase price to acquire Fit Pay was $10,104,184 of which $100,000 was paid by the Company in cash and $10,004,184 in non-cash consideration.

The non-cash consideration was comprised of a $851,842 seller note, $3,289,161 of common stock issued to the sellers, Series C preferred stock issued to sellers of $1,807,300 and $4,055,881 in an earn-out provision. At the date of acquisition, the earn-out provision was discounted using a prime borrowing rate of 3.5%.

The Merger Agreement was accounted for under the acquisition method of accounting. The purchase price was allocated to the tangible and identifiable assets acquired and liabilities assumed of Fit Pay based upon their estimated fair values. The excess purchase price over the fair value of the underlying net assets acquired was allocated to goodwill. The Company completed its analysis of the fair value of the net assets acquired and the consideration granted through the use of an independent valuation firm and management’s preparation of estimates. The following table summarizes the assessment of the estimated fair values of the identifiable assets acquired and liabilities assumed net of cash acquired, as of the date of acquisition of May 23, 2017:

Cash	$	10,889
Accounts receivable		92,629
Other current assets		53,966
Property and equipment		31,968
Goodwill		9,119,709
Intangible assets (See Note 4)		4,137,400
Assets acquired		13,446,561

Accounts payable		165,650
Accrued liabilities		1,139,774
Customer deposits		262,414
Deferred taxes		1,774,539
Liabilities assumed		3,342,377

Net assets acquired	$	10,104,184

Goodwill arising from the transaction consists of the expected operational synergies upon combining the entity and intangibles not qualifying for separate recognition.

In connection with the Fit Pay transaction, the Company entered into an employment agreement with Michael Orlando, the former Chief Executive Officer of Fit Pay. Mr. Orlando is now the Chief Operating Officer of the Company and President of the wholly-owned subsidiary, Fit Pay. The term of the employment agreement is for one (1) year and the employment agreement includes provisions for term extensions. In addition to Mr. Orlando’s salary, the employment agreement also provides for all necessary and reasonable out-of-pocket expenses incurred in the performance of his duties under the agreement, eligibility to participate in bonus or incentive compensation plans of the Company and eligibility to receive equity awards as determined by the board of directors.

Pro Forma Financial Information

The following table summarizes the unaudited pro forma financial information assuming that the acquisition of Fit Pay occurred on January 1, 2017, and its results had been included in the Company’s financial results for the three months ended March 31, 2017. The pro forma combined amounts are based upon available information and reflect a reasonable estimate of the effects of the Fit Pay acquisition for the periods presented on the basis set forth herein. The following unaudited pro forma combined financial information is presented for informational purposes only and does not purport to represent what the financial position or results of operations would have been had the Fit Pay acquisition in fact occurred on the date assumed, nor is it necessarily indicative of the results that may be expected in future periods.

Summary of Significant Accounting Policies (Policies)	Mar. 31, 2018
Summary of Significant Accounting Policies [Abstract]
USE OF ESTIMATES IN THE FINANCIAL STATEMENTS	*Use of estimates in the financial statements* The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. The Company’s management evaluates these significant estimates and assumptions included those related to the fair value of acquired assets and liabilities, stock based compensation, derivative instruments, income taxes, accounts receivable and inventories, and other matters that affect the condensed consolidated financial statements and disclosures. Actual results could differ from those estimates.
PRINCIPLES OF CONSOLIDATION	*Principles of consolidation* The condensed consolidated financial statements include the accounts of Nxt-ID and its wholly-owned subsidiaries, 3D-ID, LogicMark and Fit Pay. Intercompany balances and transactions have been eliminated in consolidation.
CONCENTRATIONS OF CREDIT RISK	*Concentrations of Credit Risk* The Company is a party to a Master Development Agreement with World Ventures Holding, LLC (“WVH”), a related party. WVH is considered a related party since the Chief Technology Officer of WVH is a director of Nxt-ID, Inc. During the three months ended March 31, 2018 and 2017, the Company recognized revenue of $254,258 and $2,708,036, respectively from WVH. At March 31, 2018 and December 31, 2017, the Company’s accounts receivable, net balance included $995,787 and $1,364,405, respectively due from WVH.
REVENUE RECOGNITION	*Revenue Recognition* The Company primary source of revenues is from product sales to its customers. The Company recognizes revenue when persuasive evidence of an arrangement exists, the service has been rendered or product delivery has occurred, the price is fixed or readily determinable and collectability of the sale is reasonably assured. The Company’s revenue is recorded at the net amount to be received after deductions for discounts, allowances and product returns.
ACCOUNTS RECEIVABLE	*Accounts Receivable* Accounts receivable is stated at net realizable value. The Company regularly reviews accounts receivable balances and adjusts the receivable reserves as necessary whenever events or circumstances indicate the carrying value may not be recoverable. At March 31, 2018 and December 31, 2017, the Company had an allowance for doubtful accounts of $402,383.
INVENTORY	*Inventory* The Company performs regular reviews of inventory quantities on hand and evaluates the realizable value of its inventories. The Company adjusts the carrying value of the inventory as necessary with estimated valuation reserves for excess, obsolete, and slow-moving inventory by comparing the individual inventory parts to forecasted product demand or production requirements. As of March 31, 2018 inventory was comprised of $1,588,842 in raw materials and $1,408,128 in finished goods on hand. Inventory at December 31, 2017 was comprised of $1,493,995 in raw materials and $1,565,522 in finished goods on hand. The Company is required to prepay for raw materials with certain vendors until credit terms can be established. As of March 31, 2018, and December 31, 2017, the Company had prepaid inventory of $910,568 and $887,021, respectively. These prepayments were made primarily for raw materials inventory and prepaid inventory is included in prepaid expenses and other current assets on the condensed consolidated balance sheet.
GOODWILL	*Goodwill* The Company’s goodwill relates to the acquisitions of LogicMark and Fit Pay. The Company began testing goodwill for impairment in the third quarter of 2017 as it relates to the acquisition of LogicMark. The Company will begin testing the Fit Pay related goodwill for impairment annually in the second quarter of 2018. Authoritative accounting guidance allows the Company to first assess qualitative factors to determine whether it is necessary to perform the more detailed two-step quantitative goodwill impairment test. The Company performs the quantitative test if its qualitative assessment determined it is more likely than not that a reporting unit’s fair value is less than its carrying amount. The Company may elect to bypass the qualitative assessment and proceed directly to the quantitative test for any reporting units or assets. The quantitative goodwill impairment test, if necessary, is a two-step process. The first step is to identify the existence of a potential impairment by comparing the fair value of a reporting unit (the estimated fair value of a reporting unit is calculated using a discounted cash flow model) with its carrying amount, including goodwill. If the fair value of a reporting unit exceeds its carrying amount, the reporting unit’s goodwill is considered not to be impaired and performance of the second step of the quantitative goodwill impairment test is unnecessary. However, if the carrying amount of a reporting unit exceeds its fair value, the second step of the quantitative goodwill impairment test is performed to measure the amount of impairment loss to be recorded, if any. The second step of the quantitative goodwill impairment test compares the implied fair value of the reporting unit’s goodwill with the carrying amount of that goodwill. If the carrying amount of the reporting unit’s goodwill exceeds its implied fair value, an impairment loss is recognized in an amount equal to that excess. The implied fair value of goodwill is determined using the same approach as employed when determining the amount of goodwill that would be recognized in a business combination. That is, the fair value of the reporting unit is allocated to all of its assets and liabilities as if the reporting unit had been acquired in a business combination and the fair value was the purchase price paid to acquire the reporting unit. As part of the annual evaluation of the LogicMark related goodwill, the Company utilized the option to first assess qualitative factors, which include but are not limited to, economic, market and industry conditions, as well as the financial performance of LogicMark. In accordance with applicable guidance, an entity is not required to calculate the fair value of a reporting unit if, after assessing these qualitative factors, the Company determines that it is more likely than not that its reporting unit’s fair value is greater than its carrying amount. During the year ended December 31, 2017, the Company determined that it was more likely than not that the fair value of LogicMark exceeded its respective carrying amount and therefore, a quantitative assessment was not required. As of March 31, 2018, there were no triggering events which would have necessitated an interim period evaluation.
OTHER INTANGIBLE ASSETS	*Other Intangible Assets* The Company’s intangible assets are all related to the acquisitions of Fit Pay and LogicMark and are included in other intangible assets in the Company’s condensed consolidated balance sheets at March 31, 2018, and December 31, 2017. At March 31, 2018, the other intangible assets relating to the acquisition of LogicMark are comprised of patents of $3,471,980; trademarks of $1,151,618; and customer relationships of $2,712,464. At December 31, 2017, the other intangible assets are comprised of patents of $3,563,885; trademarks of $1,167,122; and customer relationships of $2,792,900. The Company will continue amortizing these intangible assets using the straight line method over their estimated useful lives which for the patents, trademarks and customer relationships are 11 years; 20 years; and 10 years, respectively. During the three months ended March 31, 2018 and 2017, the Company had amortization expense of $187,845 related to the LogicMark intangible assets. At March 31, 2018, the other intangible assets relating to the acquisition of Fit Pay, which was completed on May 23, 2017, are comprised of trademarks of $157,414; technology of $2,193,737; and customer relationships of $1,240,534. At December 31, 2017, the other intangible assets are comprised of trademarks of $181,042; technology of $2,284,739; and customer relationships of $1,336,868. The Company will continue amortizing these intangible assets using the straight line method over their estimated useful lives which for the patents, trademarks and customer relationships are 5 years; 7 years; and 6 years, respectively. During the three months ended March 31, 2018, the Company had amortization expense of $210,964 related to the Fit Pay intangible assets. As of March 31, 2018, total amortization expense estimated for the remainder of fiscal 2018 is approximately $998,000 and for each of the next five fiscal years, 2019 through 2023 the total amortization expense is estimated to be as follows: 2019 - $1,400,000; 2020 - $1,400,000; 2021 - $1,400,000; 2022 - $1,388,000; 2023 - $1,248,000.
STOCK-BASED COMPENSATION	*Stock-Based Compensation* The Company accounts for share-based awards exchanged for employee services at the estimated grant date fair value of the award. The Company accounts for equity instruments issued to non-employees at their fair value on the measurement date. The measurement of stock-based compensation is subject to periodic adjustment as the underlying equity instrument vests or becomes non-forfeitable. Non-employee stock-based compensation charges are amortized over the vesting period or as earned. Stock-based compensation is recorded in the same component of operating expenses as if it were paid in cash. The Company generally issues new shares of common stock to satisfy conversion and warrant exercises.
NET LOSS PER SHARE	*Net Loss per Share* Basic loss per share was computed using the weighted average number of common shares outstanding. Diluted loss per share includes the effect of diluted common stock equivalents. Potentially dilutive securities from the exercise of 4,602,650 warrants as of March 31, 2018 were excluded from the computation of diluted net loss per share because the effect of their inclusion would have been anti-dilutive. As of March 31, 2017, potentially dilutive securities of 1,749,805 realizable from the Series A Preferred Stock and Series B Preferred Stock, 575,000 from the convertible exchange notes and from the exercise of 1,829,049 warrants were excluded from the computation of diluted net loss per share because the effect of their inclusion would have been anti-dilutive.
RECENT ACCOUNTING PRONOUNCEMENTS	*Recent Accounting Pronouncements* In May 2017, the Financial Accounting Standards Board (the “FASB”) issued ASU 2017-09, “Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting” to provide clarity and reduce both (1) diversity in practice and (2) cost and complexity when applying the guidance in Topic 718, Compensation—Stock Compensation, to a change to the terms or conditions of a share-based payment award. The amendments in this Update provide guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. The amendments in this Update are effective for all entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. Early adoption is permitted. This ASU was adopted and it did not have a material impact on the Company’s condensed consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-01, “Business Combinations (Topic 805): Clarifying the Definition of a Business.” The amendments in this update clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of businesses. The amendments in this update provide a screen to determine when a set is not a business. If the screen is not met, it (1) requires that to be considered a business, a set must include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create output and (2) removes the evaluation of whether a market participant could replace the missing elements. The amendments in this Update are effective for all entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. This ASU was adopted and it did not have a material impact on the Company’s condensed consolidated financial statements. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows: Restricted Cash (“ASU No. 2016-18”). The amendments address diversity in practice that exists in the classification and presentation of changes in restricted cash and require that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. This ASU is effective retrospectively for fiscal years and interim periods within those years beginning after December 15, 2017. As permitted under the standard for emerging growth companies, the Company plans to adopt ASU 2016-18 in the first quarter of 2019. The Company is currently reviewing and evaluating this guidance and its impact on its condensed consolidated financial statements. In May 2016, the FASB issued ASU No. 2016-12 (“ASU 2016-12”), “Revenue from Contracts with Customers (Topic 606): Narrow- Scope Improvements and Practical Expedients.” ASU 2016-12 will affect all entities that enter into contracts with customers to transfer goods or services (that are an output of the entity’s ordinary activities) in exchange for consideration. The amendments in this update affect the guidance in ASU 2014-09 which is not yet effective, the amendments in this update affect narrow aspects of Topic 606 including among others: assessing collectability criterion, noncash consideration, and presentation of sales taxes and other similar taxes collected from customers. The effective date and transition requirements for the amendments in this update are the same as the effective date and transition requirements for ASU 2014-09. The Company is currently evaluating the effect that ASU 2016-12 will have on the Company’s financial position and results of operations. In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers ("ASU 2014-09"), which stipulates that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for such goods or services. To achieve this core principle, an entity should apply the following steps: (1) identify the contract(s) with a customer; (2) identify the performance obligations in the contract(s); (3) determine the transaction price(s); (4) allocate the transaction price(s) to the performance obligations in the contract(s); and (5) recognize revenue when (or as) the entity satisfies a performance obligation. The guidance also requires advanced disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from an entity's contracts with customers. In August 2015, the FASB issued Accounting Standards Update No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date ("ASU 2015-14"), which defers the effective date of FASB's revenue standard under ASU 2014-09 by one year for all entities and permits early adoption on a limited basis. As a result of ASU 2015-14, the guidance under ASU 2014-09 shall apply for annual reporting periods beginning after December 15, 2017, including interim reporting periods within that period. Early adoption is permitted as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within those annual periods. In March 2016, the FASB issued Accounting Standards Update No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net), which clarified the implementation guidance on principal versus agent considerations. In April 2016, the FASB issued Accounting Standards Update No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing, which clarified the implementation guidance regarding performance obligations and licensing arrangements. As permitted under the standard for emerging growth companies, the Company plans to adopt ASU 2014-09 in the first quarter of 2019 using the modified retrospective approach and recognize the cumulative effect to existing contracts in opening retained earnings on the effective date. The Company is currently reviewing and evaluating this guidance and its impact on its condensed consolidated financial statements. Therefore, the Company’s results may not be comparable with others companies in our industry until ASU 2014-09 is adopted.

Liquidity and Management Plans [Abstract]
LIQUIDITY AND MANAGEMENT PLANS	Note 2 – Liquidity And Management Plans The Company is an emerging growth entity and recorded an operating loss of $740,748 and a net loss of $1,612,813 during the three months ended March 31, 2018. As of March 31, 2018 the Company had working capital of $738,830 and stockholders’ equity of $18,225,489. Such factors raise substantial doubt about the entity’s ability to sustain operations for at least one year from the issuance of these financial statements. Given the Company’s cash position at March 31, 2018 and its projected cash flow from operations, the Company believes that it will have sufficient capital to sustain operations over the next twelve months following the date of this filing to alleviate such substantial doubt. In order to execute the Company’s long-term strategic plan to develop and commercialize its core products, fulfill its product development commitments and fund its obligations as they come due, the Company may need to raise additional funds, through public or private equity offerings, debt financings, or other means. Should the Company not be successful in obtaining the necessary financing, or generate sufficient revenue to fund its operations, the Company would need to engage in certain cost containment efforts, and/or curtail certain of its operational activities. The Company can give no assurance that any cash raised subsequent to March 31, 2018 will be sufficient to execute its business plan or meet its obligations. The Company can give no assurance that additional funds will be available on reasonable terms, or available at all, or that it will generate sufficient revenue to alleviate these conditions.
