Notes to Financial Statements
Organization, Consolidation, Basis of Presentation, Business Description and Accounting Policies [Text Block]	NOTE 1. Company Table Trac was formed under the laws of the State of Nevada in June 1995. The Company provides system sales and technical support to casinos. System sales include installation, custom casino system configuration and training. In addition, license and technical support are provided under an annual license and service contract. Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles (GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. The Company's use of estimates and assumptions include: for revenue recognition, determining collectability, the nature and timing of satisfaction of performance obligations, and determining the standalone selling price (SSP) of performance obligations, and other obligations, realizability of accounts receivable, the valuation of deferred tax assets and liabilities and inventory valuation. Actual results could differ from those estimates and the difference could be significant. Concentrations of Risk Cash Deposits in Excess of Federally Insured Limits The Company maintains its cash balances at two $250,000. may Major Customers The following table summarizes major customer's information for the years ended December 31, 2020 2019 For the Years ended December 31, 2020 2019 % Revenues % AR % Revenues % AR (As Restated) (As Restated) Major 10.2 % 40.5 % 30.6 % 49.4 % All Others 89.8 % 59.5 % 69.4 % 50.6 % Total 100.0 % 100.0 % 100.0 % 100.0 % A major customer is defined as any customer that represents at least 10% Revenue Recognition The Company derives revenues from the sales of systems, licenses and maintenance fees, and services, and rental agreements. System Sales Revenue is recognized upon transfer of control of promised products and services to customers in an amount that reflects the consideration we expect to receive in exchange for those products or services. We enter into contracts that can include various combinations of products and services, which are generally capable of being distinct and accounted for as separate performance obligations. Revenue is recognized net of any taxes collected, when applicable from customers, which are subsequently remitted to governmental authorities. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is a unit of account in ASC 606. Management's assessment of collectability at both contract inception and on an ongoing basis resulted in the determination that some of our contracts did not not not Maintenance Revenue Maintenance revenue is recognized ratably over the contract period. The SSP for maintenance is based upon the renewal rate for contracted services. Service Revenue and Other Revenue Service revenue is recognized upon completion of the services and are billed in arrears. The SSP for service revenue is established based upon actual selling prices for the services or prior similar arrangements. The Company offers qualified customers a licensing agreement. Licensing revenue is recognized after the intellectual property (CMS system), the performance obligation, is delivered and in its operational and functional state. The stand-alone selling price for licensing revenue is established based upon actual selling prices for the license. The following table summarizes disaggregated revenues by major product line for the years ended December 31, 2020 2019 Years ended December 31, 2020 2019 2020 2019 (As Restated) (As Restated) (percent of revenues) System revenue $ 1,614,594 $ 3,662,774 36.7 % 46.3 % Maintenance revenue 2,615,024 2,829,740 59.4 % 35.8 % Service and other revenue 171,823 1,415,947 3.9 % 17.9 % Total revenues $ 4,401,441 $ 7,908,461 100.0 % 100.0 % Significant Judgments Contracts with customers often include promises to transfer multiple products and services to a customer. Determining whether products and services are considered distinct performance obligations that should be accounted for separately versus together may Judgment is required to determine the SSP for each distinct performance obligation. We use a single amount to estimate SSP when we sell a product or service separately. In instances where SSP is not not may one The collectability assessment requires the company to use judgement and consider all relevant facts and circumstances. We evaluate the interest rates in customer contracts with extended payment terms, representing a significant financing component. These rates range from approximately 1% 6% Geographic Concentrations The Company sells its technologies and services to casinos in the United States, Australia, Japan, the Caribbean and countries in both Central and South America.

Fair value estimates are at a specific point in time, based on relevant market information about the financial instrument. These estimates are subjective in nature and matters of significant judgment and therefore cannot be determined with precision. The Company considers the carrying values of its financial instruments to approximate fair value due to their short-term nature. Cash and Cash Equivalents The Company considers all highly liquid investments purchased with an original maturity of three Accounts Receivable / Allowance for Doubtful Accounts Accounts receivable are initially recorded at the invoiced amount and carried on the balance sheet at net realizable value as of each balance sheet date. For receivables related to contracts that contain an interest rate, interest is recorded upon receipt to interest income on the statements of operations. An allowance for doubtful accounts is recorded when the Company believes the amounts may not no may not not Inventory Inventory, consisting of finished goods, is stated at the lower of cost or net realizable value.

Deferred tax assets and liabilities represent the future tax consequences of the differences between the financial statement carrying amounts of assets and liabilities versus the tax basis of assets and liabilities. Under this method, deferred tax assets are recognized for deductible temporary differences and operating loss and tax credit carryforwards. Deferred tax liabilities are recognized for taxable temporary differences.

Research and development expenses were $283,421 $272,156 December 31, 2020 2019 Stock-based Compensation The Company measures and recognizes compensation expense for all stock-based payment awards made to employees, directors and non-employees. The compensation expense for the Company's stock-based payments is based on estimated fair values at the time of the grant. The Company estimates the fair value of restricted stock awards on the date of grant using the closing traded price on that date. The Company's restricted stock awards are subject to vesting requirements and the corresponding compensation is recorded ratably over the service period. Basic and Diluted Earnings Per Share Basic earnings per share is computed by dividing net income by the weighted average shares outstanding during the reporting period. Diluted earnings per share is computed similar to basic earnings per share except that the weighted average shares outstanding are increased to include additional shares from the assumed exercise of stock options and restricted stock shares subject to vesting. The number of additional shares is calculated by assuming that outstanding stock options were exercised and that the proceeds from the exercise were used to acquire shares of common stock at the average market price during the reporting period. Restricted stock shares are included in dilutive shares as of the beginning of the period in which the vesting conditions are satisfied. (See Note 9

Accounting Policies [Abstract]
Company [Policy Text Block]	Company Table Trac was formed under the laws of the State of Nevada in June 1995. The Company provides system sales and technical support to casinos. System sales include installation, custom casino system configuration and training. In addition, license and technical support are provided under an annual license and service contract.
Use of Estimates, Policy [Policy Text Block]	Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles (GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. The Company's use of estimates and assumptions include: for revenue recognition, determining collectability, the nature and timing of satisfaction of performance obligations, and determining the standalone selling price (SSP) of performance obligations, and other obligations, realizability of accounts receivable, the valuation of deferred tax assets and liabilities and inventory valuation. Actual results could differ from those estimates and the difference could be significant.
Concentration Risk, Credit Risk, Policy [Policy Text Block]	Concentrations of Risk Cash Deposits in Excess of Federally Insured Limits The Company maintains its cash balances at two $250,000. may Major Customers The following table summarizes major customer's information for the years ended December 31, 2020 2019 For the Years ended December 31, 2020 2019 % Revenues % AR % Revenues % AR (As Restated) (As Restated) Major 10.2 % 40.5 % 30.6 % 49.4 % All Others 89.8 % 59.5 % 69.4 % 50.6 % Total 100.0 % 100.0 % 100.0 % 100.0 % A major customer is defined as any customer that represents at least 10%
Revenue [Policy Text Block]	Revenue Recognition The Company derives revenues from the sales of systems, licenses and maintenance fees, and services, and rental agreements. System Sales Revenue is recognized upon transfer of control of promised products and services to customers in an amount that reflects the consideration we expect to receive in exchange for those products or services. We enter into contracts that can include various combinations of products and services, which are generally capable of being distinct and accounted for as separate performance obligations. Revenue is recognized net of any taxes collected, when applicable from customers, which are subsequently remitted to governmental authorities. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is a unit of account in ASC 606. Management's assessment of collectability at both contract inception and on an ongoing basis resulted in the determination that some of our contracts did not not not Maintenance Revenue Maintenance revenue is recognized ratably over the contract period. The SSP for maintenance is based upon the renewal rate for contracted services. Service Revenue and Other Revenue Service revenue is recognized upon completion of the services and are billed in arrears. The SSP for service revenue is established based upon actual selling prices for the services or prior similar arrangements. The Company offers qualified customers a licensing agreement. Licensing revenue is recognized after the intellectual property (CMS system), the performance obligation, is delivered and in its operational and functional state. The stand-alone selling price for licensing revenue is established based upon actual selling prices for the license. The following table summarizes disaggregated revenues by major product line for the years ended December 31, 2020 2019 Years ended December 31, 2020 2019 2020 2019 (As Restated) (As Restated) (percent of revenues) System revenue $ 1,614,594 $ 3,662,774 36.7 % 46.3 % Maintenance revenue 2,615,024 2,829,740 59.4 % 35.8 % Service and other revenue 171,823 1,415,947 3.9 % 17.9 % Total revenues $ 4,401,441 $ 7,908,461 100.0 % 100.0 % Significant Judgments Contracts with customers often include promises to transfer multiple products and services to a customer. Determining whether products and services are considered distinct performance obligations that should be accounted for separately versus together may Judgment is required to determine the SSP for each distinct performance obligation. We use a single amount to estimate SSP when we sell a product or service separately. In instances where SSP is not not may one The collectability assessment requires the company to use judgement and consider all relevant facts and circumstances. We evaluate the interest rates in customer contracts with extended payment terms, representing a significant financing component. These rates range from approximately 1% 6% Geographic Concentrations The Company sells its technologies and services to casinos in the United States, Australia, Japan, the Caribbean and countries in both Central and South America.

Fair Value of Financial Instruments, Policy [Policy Text Block]	Fair Value of Financial Instruments The Company's financial instruments consist of cash, accounts receivable, accounts payable and accrued expenses and debt. Fair value estimates are at a specific point in time, based on relevant market information about the financial instrument. These estimates are subjective in nature and matters of significant judgment and therefore cannot be determined with precision. The Company considers the carrying values of its financial instruments to approximate fair value due to their short-term nature.

Income Tax, Policy [Policy Text Block]	Income Taxes The Company accounts for income taxes by following the asset and liability approach to accounting for income taxes. Deferred tax assets and liabilities represent the future tax consequences of the differences between the financial statement carrying amounts of assets and liabilities versus the tax basis of assets and liabilities. Under this method, deferred tax assets are recognized for deductible temporary differences and operating loss and tax credit carryforwards. Deferred tax liabilities are recognized for taxable temporary differences. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not not not not The Company files income tax returns in the U.S. federal jurisdiction and various state jurisdictions.

Share-based Payment Arrangement [Policy Text Block]	Stock-based Compensation The Company measures and recognizes compensation expense for all stock-based payment awards made to employees, directors and non-employees. The compensation expense for the Company's stock-based payments is based on estimated fair values at the time of the grant. The Company estimates the fair value of restricted stock awards on the date of grant using the closing traded price on that date. The Company's restricted stock awards are subject to vesting requirements and the corresponding compensation is recorded ratably over the service period.
Earnings Per Share, Policy [Policy Text Block]	Basic and Diluted Earnings Per Share Basic earnings per share is computed by dividing net income by the weighted average shares outstanding during the reporting period. Diluted earnings per share is computed similar to basic earnings per share except that the weighted average shares outstanding are increased to include additional shares from the assumed exercise of stock options and restricted stock shares subject to vesting. The number of additional shares is calculated by assuming that outstanding stock options were exercised and that the proceeds from the exercise were used to acquire shares of common stock at the average market price during the reporting period. Restricted stock shares are included in dilutive shares as of the beginning of the period in which the vesting conditions are satisfied. (See Note 9
