Nature of Business and Summary of Significant Accounting Policies [Abstract]
Nature of business 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 September 30, 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 September 30, 2016, the Company’s accumulated deficit was $129,843. The Company has primarily met its working capital needs through the sale of debt and equity securities. As of September 30, 2016, the Company’s cash balance was $140. 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 In January 2016, the FASB issued ASU 2016-01, Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities In February 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. The guidance is effective for annual periods after December 15, 2018. In March 2016 the FASB issued ASU No. 2016-09 Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. ASU 2016-09 provides for simplification involving several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. In addition to these simplifications, ASU 2016-09 also eliminates the guidance in Topic 718 that was indefinitely deferred shortly after the issuance of FASB Statement No. 123 (revised 2004), Share-Based Payment. Early adoption is permitted and the application of the guidance is different for each update included within ASU 2016-09. The guidance is effective for annual periods after December 15, 2016. In May 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2016-12 Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients. ASU 2016-12 provides for improvements and practical expedients for specific areas of Topic 606. In April 2016, the FASB issued ASU No. 2016-10 Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing. ASU 2016-10 provides for clarification of two aspects of Topic 606: identifying performance obligations and the licensing implementation guidance. In March 2016, the FASB issued ASU No. 2016-08 Revenue from Contracts with Customers (Topic 606) - Principal versus Agent Considerations (Reporting Revenue Gross versus Net). ASU No. 2016 - 08 requires an entity to determine whether the nature of its promise to provide goods or services to a customer is performed in a principal or agent capacity and to recognize revenue in a gross or net manner based on its principal/agent designation. ASUs 2016-12, 2016-10 and 2016-08 allow for companies to choose to apply the standard retrospectively to each prior reporting period presented (full retrospective application) or retrospectively with the cumulative effect of initially applying the standard as an adjustment to the opening balance of retained earnings of the annual reporting period that includes the date of initial application (modified retrospective application). Each guidance is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. Early application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. iSign is in the process of evaluating the impact of the new guidance on the Company’s financial position, results of operations and cash flows.

Intangible Assets [Abstract]
Intangible assets	3. Intangible Assets 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 intangible assets 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 and nine months ended September 30, 2016 that would impact this conclusion. Amortization of intangible asset costs was $81 and $242 for the three and nine-month periods ended September 30, 2016 and $87 and $260 for the three- and nine-month periods ended September 30, 2015.

Net Loss Per Share [Abstract]
Net loss per share	4. Net loss per share The Company calculates basic net loss per share based on the weighted average number of shares outstanding, and when applicable, diluted net income per share, which is based on the weighted average number of shares and potential dilutive shares outstanding. The Company’s Preferred Shareholders converted all of their Preferred Stock into shares of Common Stock on May 19, 2016. The following table lists shares and warrants that were excluded from the calculation of diluted earnings per share as the exercise of such options and warrants and the conversion of such preferred shares would be anti-dilutive: For the Nine Months Ended September 30, 2016 September 30, 2015 Stock options 71 85 Warrants 1,756 190 Preferred shares as if converted Series A-1 Preferred Stock - 5 Series B Preferred Stock - 244 Series C Preferred Stock - 190 Series D-1 Preferred Stock - 280 Series D-2 Preferred Stock - 100

Debt [Abstract]
Debt	5. Debt Note payable In the 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. Promissory notes with a principal amount of $1,068 plus accrued interest converted into shares of our Common Stock on May 19, 2016. The notes and accrued interest converted at a price of $1.74 per share into 683 shares of our Common Stock. The holders of the notes also received 854 warrants to purchase 854 shares of Common Stock. Such warrants have a 5-year term and are exercisable at a price of $2.175 per share. The Company ascribed a relative fair value to the warrants using the Black-Scholes-Merton valuation model of $586, which was charged to additional paid-in capital during the quarter ended June 30, 2016. In August 2016, the Company issued long-term unsecured convertible promissory notes to investors and affiliates of the Company aggregating $240 in cash. The notes are mandatorily convertible to common stock at a conversion rate of $0.91 per share upon closing a new debt and or equity financing of at least $500 in aggregate proceeds. The notes bear interest at the rate of 1% per annum and are due December 31, 2017. The holders shall also receive, on a pro rata basis, cash payments payable from 3% of the revenue actually received by the Company from its European customer, not to exceed one and one-half (1.5) times the aggregate principal amount of the notes. Such cash payments only occur if the notes are converted into Common Stock. The convertible notes contained an embedded beneficial conversion feature having an intrinsic value of $103 at the issuance date, for which the Company recorded a discount to the long-term notes payable and a corresponding additional paid-in capital attributable to the beneficial conversion feature. The discount will be amortized using the effective interest method over the term of the notes. The Company recorded $7 in debt discount amortization expense associated with these notes for the three and nine month period ended September 30, 2016. The proceeds from the notes were used to pay off the $200 promissory note outstanding plus accrued interest that was due on August 24, 2016. In September 2016, the Company issued demand promissory notes to affiliates of the Company aggregating $100 in cash. The notes bear interest at the rate of 1% per annum and are due on demand. In addition, the affiliate will be a paid a financing fee of 10% of the face value of the demand notes upon such repayment of the demand notes or their exchange into the next financing. In the event the demand notes are not repaid or exchanged by December 31, 2016, the demand notes will automatically be exchanged into unsecured convertible promissory notes, substantially with the same terms described in the previous paragraph.

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 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 September 30, 2016 and December 31, 2015, respectively. The previously outstanding short-term note payable balance of $200 in aggregate principal was fully paid off on August 24, 2016 and in conjunction, the related derivative liability balance of $156 was extinguished. Changes in the fair market value of the Level 3 derivative liability for the nine-month periods ended September 30, 2016 and September 30, 2015 are as follows: For the Nine Months Ended September 30, September 30, 2015 Balance at January 1 $ 330 $ - Net gain on derivative liability (330 ) - Balance at September 30 $ - $ -

Equity (Deficit) [Abstract]
Equity (Deficit)	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 nine months ended September 30, 2016 and 2015, was approximately 12.34% and 7.89%, 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 using the accrual method over the vesting period of the options. The fair value calculations are based on the following assumptions: Nine Months Ended September 30, 2016 Nine Months Ended September 30, 2015 Risk free interest rate 0.04% - 3.19% 0.04% - 3.28% Expected life (years) 2.82 – 7.00 3.26 – 6.33 Expected volatility 112.75% - 198.90% 120.74% – 198.38% Expected dividends None None There were no stock options granted during the three and nine month periods ended September 30, 2016. There were no stock options exercised during the three- and nine-months ended September 30, 2016. There were no stock options granted during the three month period ended September 30, 2015. The Company granted 29 stock options during the nine months ended September 30, 2015 at a weighted average exercise price of $28.13 per share. There were no stock options exercised during the three- and nine-months ended September 30, 2015. The following table summarizes the allocation of stock-based compensation expense related to stock option grants for the three- and nine-month periods ended September 30, 2016 and 2015.

The unrecognized compensation expense is expected to be realized over a weighted average period of 2.2 years. Sale of Common Stock and Conversion of Preferred Stock, Short-term Debt and Deferred Compensation On May 19, 2016, the Company closed an underwritten public offering of 690 shares of common stock at a public offering price of $1.74 per share. In addition, the Company sold 345 warrants, at a public offering price of $0.01 per warrant, to purchase shares of Common Stock. The warrants expire on May 18, 2021 and have an exercise price of $2.175 per share. The Company raised gross cash proceeds of $1,204 before deducting underwriting discounts and commissions and other offering expenses of $780. As a result of the consummation of the offering, each series of the Company’s outstanding preferred stock, including accrued and unpaid dividends through May 19, 2016, were converted into shares of common stock. As a result of the Amendments to the Certificates of Designations to all classes of Preferred Stock and pursuant to the terms thereof, the conversion price of the Company’s Preferred Stock was reduced.

Nature of Business and Summary of Significant Accounting Policies [Abstract]
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. 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	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 September 30, 2016, the Company’s accumulated deficit was $129,843. The Company has primarily met its working capital needs through the sale of debt and equity securities. As of September 30, 2016, the Company’s cash balance was $140. 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	Accounting Changes and Recent Accounting Pronouncements In January 2016, the FASB issued ASU 2016-01, Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities In February 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. The guidance is effective for annual periods after December 15, 2018. In March 2016 the FASB issued ASU No. 2016-09 Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. ASU 2016-09 provides for simplification involving several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. In addition to these simplifications, ASU 2016-09 also eliminates the guidance in Topic 718 that was indefinitely deferred shortly after the issuance of FASB Statement No. 123 (revised 2004), Share-Based Payment. Early adoption is permitted and the application of the guidance is different for each update included within ASU 2016-09. The guidance is effective for annual periods after December 15, 2016. In May 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2016-12 Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients. ASU 2016-12 provides for improvements and practical expedients for specific areas of Topic 606. In April 2016, the FASB issued ASU No. 2016-10 Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing. ASU 2016-10 provides for clarification of two aspects of Topic 606: identifying performance obligations and the licensing implementation guidance. In March 2016, the FASB issued ASU No. 2016-08 Revenue from Contracts with Customers (Topic 606) - Principal versus Agent Considerations (Reporting Revenue Gross versus Net). ASU No. 2016 - 08 requires an entity to determine whether the nature of its promise to provide goods or services to a customer is performed in a principal or agent capacity and to recognize revenue in a gross or net manner based on its principal/agent designation. ASUs 2016-12, 2016-10 and 2016-08 allow for companies to choose to apply the standard retrospectively to each prior reporting period presented (full retrospective application) or retrospectively with the cumulative effect of initially applying the standard as an adjustment to the opening balance of retained earnings of the annual reporting period that includes the date of initial application (modified retrospective application). Each guidance is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. Early application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. iSign is in the process of evaluating the impact of the new guidance on the Company’s financial position, results of operations and cash flows.
