Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of business, basis of presentation and summary of significant accounting policies	1. Nature of Business and Summary of Significant Accounting Policies Nature of Business On January 21, 2016, iSign Solutions Inc. (the "Company" or "iSign") filed a Certificate of Amendment to its Amended and Restated Certificate of Incorporation (the "Certificate of Amendment") with the Secretary of State of the State of Delaware to effect a 1-for-1,250 reverse split of the Company's outstanding shares of common stock. The reverse split became effective on January 22, 2016. The information with respect to common stock for the period ended March 31, 2015 has been retroactively restated to give effect to the 1-for-1,250 reverse split. iSign Solutions Inc. and its subsidiary is a leading supplier of digital transaction management (DTM) software enabling the paperless, secure and cost-effective management and authentication of document-based transactions. iSign's solutions encompass a wide array of functionality and services, including electronic signatures, simple-to-complex workflow management and various options for biometric authentication. These solutions are available across virtually all enterprise, desktop and mobile environments as a seamlessly integrated platform for both ad-hoc and fully automated transactions. iSign's platform can be deployed both on premise and as a cloud-based ("SaaS") service, with the ability to easily transition between deployment models. The Company is headquartered in Redwood Shores, California. The Company's products include SignatureOne® Ceremony™ Server, the iSign® suite of products and services, including iSign® Enterprise and iSign® Console™, and Sign-it® programs. Basis of Presentation The financial information contained herein should be read in conjunction with the Company's consolidated audited financial statements and notes thereto included in its Annual Report on Form 10-K for the year ended December 31, 2015. The accompanying unaudited condensed consolidated financial statements of the Company have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America ("GAAP") for complete consolidated financial statements. In the opinion of management, the unaudited condensed consolidated financial statements included in this quarterly report reflect all adjustments (consisting only of normal recurring adjustments) that the Company considers necessary for a fair presentation of its financial position at the dates presented and the Company's results of operations and cash flows for the periods presented. The Company's interim results are not necessarily indicative of the results to be expected for the entire year. Going Concern The accompanying unaudited condensed consolidated financial statements have been prepared assuming that the Company will continue as a going concern. The Company has incurred significant cumulative losses since its inception and, at March 31, 2016 the Company's accumulated deficit was $128,448. The Company has primarily met its working capital needs through the sale of debt and equity securities. As of March 31, 2016, the Company's cash balance was $313. These factors raise substantial doubt about the Company's ability to continue as a going concern. There can be no assurance that the Company will be successful in securing adequate capital resources to fund planned operations or that any additional funds will be available to the Company when needed, or if available, will be available on favorable terms or in amounts required by the Company. If the Company is unable to obtain adequate capital resources to fund operations, it may be required to delay, scale back or eliminate some or all of its operations, which may have a material adverse effect on the Company's business, results of operations and ability to operate as a going concern. The unaudited condensed consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty. Accounting Changes and Recent Accounting Pronouncements On February 25, 2016, the Financial Accounting Standards Board (FASB) issued an Accounting Standards Update (ASU) 2016, Leases (Topic 842) intended to improve financial reporting about leasing transactions. which requires companies to report capital and operating leases with a term of 12 Months or longer on their balance sheets. Disclosure requirements of the leasing arrangement will include qualitative and quantitative information about the amounts recorded in the financial statements. Implementation of ASU 2016 is not expected to have a material impact on the Company's financial position, results of operations and cash flows.

Patents	3. Intangible Assets, Net The Company performs an intangible asset impairment analysis at least annually or whenever circumstances or events indicate such assets might be impaired. The Company would recognize an impairment charge in the event the net book value of such assets exceeded the future undiscounted cash flows attributable to such assets. Management completed an analysis of the Company's technology as of December 31, 2015. Based on that analysis, the Company concluded that no impairment of the carrying value of the intangible assets existed. The Company believes that no events or circumstances changed during the three months ended March 31, 2016 that would impact this conclusion. Amortization of intangible asset costs was $81 for the three months ended March 31, 2016 and $87 for the three months ended March 31, 2015, respectively.

Short-term notes payable [Abstract]
Debt	5. Debt Short-term notes payable: In fourth quarter of 2015, the Company entered into unsecured convertible promissory note purchase agreements with investors and affiliates of the Company aggregating $1,268 in cash. The principal amount of the unsecured convertible promissory notes issued in connection with the Company's unsecured debt financing in November and December 2015 bear interest at a rate of 24% per year, are due on August 25, 2016 and are convertible into shares of our Common Stock at the holder's option (i) prior to maturity, in the event the Company consummates an SEC registered public offering of shares of common stock, at a conversion price that is 30% less than the price to the public of the Common Stock in the public offering, or (ii) up to 60 days after maturity, at a conversion price based upon a Company pre-money valuation of $5,000,000, as determined by taking into account the outstanding shares of Common Stock and Preferred Stock, on an as-converted basis, on the maturity date of the note; provided, that following such conversion after the maturity date, each holder that converted such note will also receive cash payments, payable from 1.5% for each $100,000 of notes converted of the revenue received by the Company from its European customer to be paid quarterly on a pro rata basis, with any and all other holders who converted their notes; provided, further, however, that the total amount of cash payments that the holder will be entitled to receive will not exceed three times the aggregate principal amount of each holder's note. The conversion option included within the unsecured convertible promissory notes was deemed to be an embedded derivative, which required the Company to bifurcate and separately account for the embedded derivative as a separate liability on the consolidated balance sheets at the estimated fair value upon issuance. The Company estimated the fair value of the derivative liability to be $330 upon issuance of the notes. The amount of short-term debt recorded on the balance sheets is net of the amount of the derivative liability. The Company recorded $106 and $0 in debt discount amortization expense associated with the notes for the three months ended March 31, 2016 and 2015, respectively.

Derivative Liability

Derivative liability [Abstract]
Derivative Liability	6. Derivative Liability The Company has determined that a contract that would otherwise meet the definition of a derivative but is both (a) indexed to the Company's own stock and (b) classified in stockholders' deficit in the statement of financial position would not be considered a derivative financial instrument. The Company applies a two-step model in determining whether a financial instrument or an embedded feature is indexed to an issuer's own stock and thus able to qualify for the scope exception. In November and December 2015, the Company entered into unsecured convertible promissory note purchase agreements with investors and affiliates of the Company. The accounting for the unsecured convertible notes, which are convertible into shares of our common stock, requires us to bifurcate the conversion feature and account for it as a derivative liability at the estimated fair value upon issuance. The Company used a Monte Carlo simulation to value the conversion feature with the following assumptions: As of March 31, 2016 Common Stock price $ 2.81 Convertible debt principal amount $ 1,268,000 Term (years) 0.08 to 0.40 Expected volatility 111% Convertible debt interest rate 24% Trials (each trial equals 150,000 iterations) 10 Discount to IPO/next round 30% The fair value framework requires a categorization of assets and liabilities into three levels based upon the assumptions (inputs) used to price the assets and liabilities. Level 1 provides the most reliable measure of fair value, whereas Level 3 generally requires significant management judgment. The three levels are defined as follows: Level 1: Applies to assets or liabilities for which there are quoted prices in active markets for identical assets or liabilities. Level 2: Applies to assets or liabilities for which there are inputs other than quoted prices that are observable for the asset or liability such as quoted prices for similar assets or liabilities in active markets; quoted prices for identical assets or liabilities in markets with insufficient volume or infrequent transactions (less active markets); or model-derived valuations in which significant inputs are observable or can be derived principally from, or corroborated by, observable market data. Level 3: Applies to assets or liabilities for which there are unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of the assets or liabilities. There were no financial assets or liabilities measured at fair value, with the exception of cash and cash equivalents (level 1) and the above mentioned derivative liability (level 3) as of March 31, 2016 and December 31, 2015, respectively. The fair value of the conversion feature (on the unsecured convertible promissory notes) derivative liability at March 31, 2016 and December 31, 2015 was $305 and $330, respectively. Changes in the fair value of the level 3 derivative liability for the three month period ended March 31, 2016 are as follows: Derivative Liability Balance at January 1, 2016 $ 330 Gain on derivative liability (25) Balance at March 31, 2016 $ 305

Stockholders' Equity [Abstract]
Stockholders' Equity	7. Equity (Deficit) Stock-based compensation expense is based on the estimated grant date fair value of the portion of stock-based payment awards that are ultimately expected to vest during the period. The grant date fair value of stock-based awards to employees and directors is calculated using the Black-Scholes-Merton valuation model. Forfeitures of stock-based payment awards are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The estimated average forfeiture rate for the three months ended March 31, 2016 and 2015 was approximately 11.89% and 7.57%, respectively, based on historical data. Valuation and Expense Information: The weighted-average fair value of stock-based compensation is based on the Black-Scholes-Merton valuation model. Forfeitures are estimated and it is assumed no dividends will be declared. The estimated fair value of stock-based compensation awards to employees is amortized over the vesting period of the options. The fair value calculations are based on the following assumptions: Three Months Ended Three Months Ended Risk free interest rate 0.04% - 3.19% 0.04% - 3.73% Expected term (years) 2.82 - 7.00 3.26 - 7.00 Expected volatility 112.75% - 198.90% 91.99% - 198.38% Expected dividends None None There were no stock options granted, and no stock options exercised during the three months ended March 31, 2016. The Company granted 29 stock options during the three months ended March 31, 2015 at a weighted average exercise price of $28.13 per share. No stock options were exercised during the three month period ended March 31, 2015.

Summary of Significant Accounting Policies
Basis of Presentation	Basis of Presentation The financial information contained herein should be read in conjunction with the Company's consolidated audited financial statements and notes thereto included in its Annual Report on Form 10-K for the year ended December 31, 2015.

Forfeitures of stock-based payment awards are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The estimated average forfeiture rate for the three months ended March 31, 2016 and 2015 was approximately 11.89% and 7.57%, respectively, based on historical data. Valuation and Expense Information: The weighted-average fair value of stock-based compensation is based on the Black-Scholes-Merton valuation model. Forfeitures are estimated and it is assumed no dividends will be declared. The estimated fair value of stock-based compensation awards to employees is amortized over the vesting period of the options.
