Basis of Presentation	1. Basis of Presentation The accompanying unaudited condensed consolidated financial statements include the accounts of Identiv, Inc. and its wholly owned subsidiaries The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments, consisting of normal recurring adjustments, considered necessary for a fair presentation of the Company’s unaudited condensed consolidated financial statements have been included. The results of operations for the three and nine months ended September 30, 2022 are not necessarily indicative of the results that may be expected for the year ending December 31, 2022 or any future period. The unaudited condensed consolidated balance sheet as of December 31, 2021 has been derived from audited consolidated financial statements at that date, but does not include all disclosures required by U.S. GAAP for complete financial statements.

Significant Accounting Policies and Recent Accounting Pronouncements	2. Significant Accounting Policies and Recent Accounting Pronouncements Significant Accounting Policies No material changes have been made to the Company's significant accounting policies disclosed in Note 2, Significant Accounting Policies and Recent Accounting Pronouncements Recent Accounting Pronouncements In June 2016, the Financial Accounting Standards Board (“FASB”) In February 2020, the FASB issued ASU 2020-02, which provides guidance regarding methodologies, documentation, and internal controls related to expected credit losses. The subsequent amendments will have the same effective date and transition requirements as ASU No. 2016-13. Early adoption is permitted. Topic 326 requires a modified retrospective approach by recording a cumulative-effect adjustment to retained earnings as of the beginning of the period of adoption. The Company adopted this standard on January 1, 2022, and it did not have a material impact on the Company’s condensed consolidated financial statements.

Revenue

Revenue From Contract With Customer [Abstract]
Revenue	3. Revenue Revenue Recognition Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration the Company expects to receive in exchange for those products or services. The Company enters into contracts that can include various combinations of its products, software licenses, and services, which are generally capable of being distinct and accounted for as separate performance obligations. For contracts with multiple performance obligations, the Company allocates the transaction price of the contract to each performance obligation, generally on a relative basis using its standalone selling price. The stated contract value is generally the transaction price to be allocated to the separate performance obligations. Revenue is recognized net of any taxes collected from customers that are subsequently remitted to governmental authorities. Nature of Products and Services The Company derives revenues from sales of hardware products, software licenses, subscriptions, professional services, software maintenance and support, and extended hardware warranties. Hardware Product Revenue — Guarantees Software License Revenue — Subscription Revenue the right to take possession of the software supporting the subscription service, or if applicable, any hardware devices at any time during the contract period, and as such are not considered separate performance obligations. Revenue is recognized ratably on a straight-line basis over the term of the contract beginning when the service is made available to the customer. Subscription contract terms range from month-to-month to six years in length and are billed monthly or annually. Professional Services Revenue — Software Maintenance and Support Revenue — one-or three-year Extended Hardware Warranties Revenue — two Performance Obligation When Performance Obligation is Typically Satisfied When Payment is Typically Due How Standalone Selling Price is Typically Estimated Hardware products When customer obtains control of the product (point-in-time) Within 30-60 days of shipment Observable in transactions without multiple performance obligations Software licenses When license is delivered to customer or made available for download, and the applicable license period has begun (point-in-time) Within 30-60 days of the beginning of license period Established pricing practices for software licenses bundled with software maintenance, which are separately observable in renewal transactions Subscriptions Ratably over the course of the subscription term (over time) In advance of subscription term Contractually stated or list price Professional services As services are performed and/or when contract is fulfilled (point-in-time) Within 30-60 days of delivery Observable in transactions without multiple performance obligations Software maintenance and support services Ratably over the course of the support contract (over time) Within 30-60 days of the beginning of the contract period Observable in renewal transactions Extended hardware warranties Ratably over the course of the support contract (over time) Within 30-60 days of the beginning of the contract period Observable in renewal transactions Significant Judgments The Company’s contracts with customers often include promises to transfer multiple products and services to a customer. For such arrangements, the Company allocates the transaction price to each performance obligation based on its relative standalone selling price (“SSP”). Judgment is required to determine the SSP for each distinct performance obligation in a contract. For the majority of items, the Company estimates SSP using historical transaction data. The Company uses a range of amounts to estimate SSP when it sells each of the products and services separately and needs to determine whether there is a discount to be allocated based on the relative SSP of the various products and services. In instances where SSP is not directly observable, such as when the product or service is not sold separately, the Company determines the SSP using information that may include market conditions and other observable inputs. The determination of SSP is an ongoing process and information is reviewed regularly in order to ensure SSPs reflect current information or trends. Disaggregation of Revenue The Company disaggregates revenue from contracts with customers based on the timing of transfer of goods or services to customers (point-in-time or over time) and geographic region based on the shipping location of the customer. The geographic regions that are tracked are the Americas, Europe and the Middle East, and Asia-Pacific regions. Total net revenue based on the disaggregation criteria described above is as follows (in thousands): Three Months Ended September 30, 2022 2021 Point-in- Time Over Time Total Point-in- Time Over Time Total Americas $ 20,412 $ 539 $ 20,951 $ 18,820 $ 847 $ 19,667 Europe and the Middle East 3,544 107 3,651 3,131 92 3,223 Asia-Pacific 6,364 30 6,394 6,207 — 6,207 Total $ 30,320 $ 676 $ 30,996 $ 28,158 $ 939 $ 29,097 Nine Months Ended September 30, 2022 2021 Point-in- Time Over Time Total Point-in- Time Over Time Total Americas $ 52,898 $ 2,582 $ 55,480 $ 46,598 $ 2,425 $ 49,023 Europe and the Middle East 11,141 332 11,473 9,026 283 9,309 Asia-Pacific 16,931 30 16,961 16,920 — 16,920 Total $ 80,970 $ 2,944 $ 83,914 $ 72,544 $ 2,708 $ 75,252 Contract Balances Amounts invoiced in advance of services being provided are accounted for as deferred revenue. Nearly all of the Company’s deferred revenue balance is related to software maintenance contracts. Payment terms and conditions vary by contract type, although payment is typically due within 30 to 60 days of contract inception. In instances where the timing of revenue recognition differs from the timing of invoicing, the Company has determined its contracts do not include a significant financing component. The primary purpose of the Company’s invoicing terms is to provide customers with simplified and predictable ways of purchasing the Company’s products and services, not to receive financing from its customers. Changes in deferred revenue during the nine months ended September 30, 2022 and 2021 were as follows (in thousands): Nine Months Ended September 30, 2022 2021 Deferred revenue, beginning of period $ 2,433 $ 2,366 Deferral of revenue billed in current period, net of recognition 2,029 1,992 Recognition of revenue deferred in prior periods (1,916 ) (1,749 ) Deferred revenue, end of period $ 2,546 $ 2,609 Unsatisfied Performance Obligations Revenue expected to be recognized in future periods related to remaining performance obligations, excluding revenue pertaining to contracts that have an original expected duration of one year or less, and contracts where revenue is recognized as invoiced, was approximately $0.7 million as of September 30, 2022. Since the Company typically invoices customers at contract inception, this amount is included in the deferred revenue balance. As of September 30, 2022, the Company expects to recognize 12% of the revenue related to these unsatisfied performance obligations during the remainder of 2022, 37% during 2023, and 51% thereafter.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	4. Fair Value Measurements The Company determines the fair values of its financial instruments based on a fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The classification of a financial asset or liability within the hierarchy is based upon the lowest level input that is significant to the fair value measurement. Under ASC 820, Fair Value Measurement and Disclosures Level 1 – Quoted prices (unadjusted) for identical assets and liabilities in active markets; Level 2 – Inputs other than quoted prices in active markets for identical assets and liabilities that are observable either directly or indirectly; and Level 3 – Unobservable inputs. Assets and Liabilities Measured at Fair Value on a Recurring Basis As of September 30, 2022 and December 31, 2021, the only assets measured and recognized at fair value on a recurring basis were nominal cash equivalents. As of September 30, 2022 and December 31, 2021, there were no liabilities measured and recognized at fair value on a recurring basis. Assets and Liabilities Measured at Fair Value on a Non-recurring Basis Certain of the Company's assets, including goodwill, intangible assets, and privately-held investments, are measured at fair value on a nonrecurring basis if impairment is indicated. Purchased intangible assets are measured at fair value primarily using discounted cash flow projections. For additional discussion of measurement criteria used in evaluating potential impairment involving goodwill and intangible assets, refer to Note 5, Goodwill and Intangible Assets As of September 30, 2022 As of September 30, 2022 and December 31, 2021, there were no liabilities that are measured and recognized at fair value on a non-recurring basis. Assets and Liabilities Not Measured at Fair Value The carrying amounts of the Company's accounts receivable, prepaid expenses and other current assets, accounts payable, and other accrued liabilities approximate fair value due to their short maturities.

Financial Liabilities	7. Financial Liabilities On February 8, 2017, the Company entered into a Loan and Security Agreement with East West Bank (“EWB”). Following subsequent amendments, on February 8, 2021 the Company amended and restated the Loan and Security Agreement in its entirety (the “Loan and Security Agreement”). The Loan and Security Agreement provided for a $20.0 million revolving loan facility subject to a borrowing base and a $4.0 million non-formula revolving loan facility that was not subject to a borrowing base. Advances under the revolving loan facility, as amended on April 30, 2021, bear interest at a per annum rate equal to the prime rate. The maturity date of the main revolving loan facility is February 8, 2023. The non-formula revolving loan facility terminated on February 7, 2022. On April 14, 2022, the Company and EWB amended the Loan and Security Agreement replacing the $20.0 million revolving loan facility subject to a borrowing base with a $20.0 million non-formula revolving loan facility with no borrowing base requirement and a maturity date of February 8, 2023. In addition, the interest rate was lowered from prime to prime minus 0.25%, and certain financial covenants were amended. The Loan and Security Agreement contains customary representations and warranties and customary affirmative and negative covenants, including, limits or restrictions on the Company’s ability to incur liens, incur indebtedness, make certain restricted payments (including dividends), merge or consolidate and dispose of assets, as well as other financial covenants. The Company’s obligations under the Loan and Security Agreement are collateralized by substantially all of its assets. As of September 30, 2022, there were no amounts outstanding and the Company was in compliance with all financial covenants under the Loan and Security Agreement.

Income Taxes	8. Income Taxes The Company conducts business globally and, as a result, files federal, state and foreign tax returns. The Company strives to resolve open matters with each tax authority at the examination level and could reach agreement with a tax authority at any time. While the Company has accrued for amounts it believes are the probable outcomes, the final outcome with a tax authority may result in a tax liability that is more or less than that reflected in the condensed consolidated financial statements. Furthermore, the Company may later decide to challenge any assessments, if made, and may exercise its right to appeal. The Company applies the provisions of, and accounted for uncertain tax positions, in accordance with ASC 740, Income Taxes The Company generally is no longer subject to tax examinations for years prior to 2017. However, if loss carryforwards of tax years prior to 2017 are utilized in the U.S., these tax years may become subject to investigation by the tax authorities. While timing of the resolution and/or finalization of tax audits is uncertain, the Company does not believe that its unrecognized tax benefits would materially change in the next 12 months. On March 11, 2021, President Biden signed the American Rescue Plan Act of 2021 (the “Act”) into law. The $1.9 trillion Act includes COVID-19 relief, as well as broader stimulus, but also includes several revenue-raising and business tax provisions. The Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) also includes several significant provisions for corporations, including the usage of net operating losses and payroll benefits. Several foreign (non-U.S.) jurisdictions in which the Company operates have taken similar economic stimulus measures. The Act and the CARES Act had no material impact on the Company’s condensed consolidated financial statements and disclosures. The Inflation Reduction Act (the “IRA”) was signed into the law on August 16, 2022. The IRA provides for a minimum tax on certain corporations having more than $1 billion in revenue, excise taxes on share buybacks and changes to various types of tax credits. The Company believes the IRA will have little to no effect on the Company’s income taxes. The Company will continue to assess as the provisions are clarified.

The determination of such allowances requires the Company to make estimates of product return rates and expected costs to repair or to replace the products under warranty. The Company currently establishes warranty reserves based on historical warranty costs for each product line combined with liability estimates based on the prior 12 months’ sales activities. If actual return rates and/or repair and replacement costs differ significantly from the Company’s estimates, adjustments to recognize additional cost of sales may be required in future periods. Historically, the warranty accrual and the expense amounts have been immaterial.

Recent Accounting Pronouncements	Recent Accounting Pronouncements In June 2016, the Financial Accounting Standards Board (“FASB”) In February 2020, the FASB issued ASU 2020-02, which provides guidance regarding methodologies, documentation, and internal controls related to expected credit losses. The subsequent amendments will have the same effective date and transition requirements as ASU No. 2016-13. Early adoption is permitted. Topic 326 requires a modified retrospective approach by recording a cumulative-effect adjustment to retained earnings as of the beginning of the period of adoption. The Company adopted this standard on January 1, 2022, and it did not have a material impact on the Company’s condensed consolidated financial statements.
