Stock-Based Compensation [Abstract]
Stock-Based Compensation	NOTE 3 - STOCK-BASED COMPENSATION  Employee Stock Purchase Plan  Under the Company’s Employee Stock Purchase Plan (“ESPP”), employees are able to acquire shares of common stock at 85 % of the price at the end of each current quarterly plan term. The most recent term ended June 30, 2016 . The ESPP is considered compensatory under current Internal Revenue Service rules. At June 30, 2016 , after giving effect to the shares issued as of that date, 90,701 shares remain available for purchase under the ESPP.  2011 Executive Incentive Compensation Plan  On March 28, 2011 the Board adopted and on May 19, 2011 the Company’s shareholders approved the Company’s 2011 Executive Incentive Compensation Plan (“2011 Incentive Plan”). The 2011 Incentive Plan authorizes incentive awards to officers, key employees and non-employee directors in the form of options (incentive and non-qualified), stock appreciation rights, restricted stock, restricted stock units, performance stock units (“deferred stock”), performance cash units, and other awards in stock, cash, or a combination of stock and cash. The 2011 Incentive Plan, as amended, allows the issuance of up to 2,000,000 shares of common stock.  During 2016 , stock options covering 305,968 shares have been awarded to key executive employees and directors. These options expire seven years from the date of award and vest 25 % each year beginning one year after the date of award. The Company also granted deferred stock awards of 93,828 shares to key employees during the first quarter of 2016 under the Company’s long-term incentive plan for performance over the 2016 to 2018 period. The actual number of shares of deferred stock, if any, that are ultimately earned by the respective employees will be determined based on achievement against performance goals at the end of the three year period ending December 31, 2018 and any shares earned will be issued in the first quarter of 2019 to those key employees still with the Company at that time.  At June 30, 2016 , 122,797 shares have been issued under the 2011 Incentive Plan, 1,147,221 shares are subject to currently outstanding options, deferred stock awards, and unvested restricted stock units, and 729,982 shares are eligible for grant under future awards.   Stock Option Plan for Directors  Shares of common stock are reserved for issuance to non-employee directors under options granted by the Company prior to 2011 under its Stock Option Plan for Non-Employee Directors (the “Director Plan”) . Under the Director Plan nonqualified stock options to acquire shares of common stock were automatically granted to each non-employee director concurrent with annual meetings of shareholders in 2010 and earlier years, with t he exercise price of options granted being the fair market value of the common stock on the date of the respective shareholder meetings. Options granted under the Director Plan expire 10 years from date of grant. No options were granted under the Director Plan in 2014 or 2015. The Company amended the Director Plan in May 2011 to prohibit future option grants. As of June 30, 2016 , there were 63,000 shares subject to outstanding options under the Director Plan.  1992 Stock Plan  Under the Company’s 1992 Stock Plan (“the Stock Plan”), shares of common stock may be issued pursuant to stock options, restricted stock or deferred stock grants to officers and key employees. Exercise prices of stock options under the Stock Plan cannot be less than fair market value of the stock on the date of grant. Rules and conditions governing awards of stock options, restricted stock and deferred stock are determined by the Compensation Committee of the Board of Directors, subject to limitations in the Stock Plan . The Company amended the Stock Plan in 2011 to prohibit future stock options or other equity awards.  At June 30, 2016 , after reserving for stock options and deferred stock awards granted in prior years and adjusting for forfeitures and issuances during the year, there were 22,008 shares reserved for issuance under the Stock Plan. The Company has not awarded stock options or deferred stock under the Stock Plan since 2011.  Changes in Stock Options Outstanding  The following table summarizes changes in the number of outstanding stock options under the 2011 Incentive Plan, the Director Plan and Stock Plan over the period December 31, 2015 to June 30, 2016 :     Weighted average Weighted average  exercise price remaining  Options per share contractual term  Outstanding – December 31, 2015 721,924 $ 11.70 4.89  Awarded 305,968 6.72  Exercised - -  Forfeited (13,721) 10.02  Outstanding – June 30, 2016 1,014,171 10.22 5.16   Exercisable at June 30, 2016 477,271 $ 11.67 4.11  Expected to vest June 30, 2016 1,014,171 10.22 5.16  The aggregate intrinsic value of all options (the amount by which the market price of the stock on the last day of the period exceeded the market price of the stock on the date of grant) outstanding at June 30, 2016 was $ 89,000 .

Debt	NOTE 9 – DEBT  Long-term Debt The mortgage on the Company’s headquarters building was payable in monthly installments and carried an interest rate of 6.83% . The mortgage matured on March 1, 2016 and the Company made payments totaling $104,000 in the first quarter of 2016 to fully settle the liability. The mortgage was secured by the building.  Line of Credit The Company has a $10,000,000 line of credit from Wells Fargo Bank. The Company had $ 3,100,000 in outstanding borrowings against the line of credit at June 30, 2016 and 2015 . Due to the revolving nature of loans under our credit facility, additional borrowings and periodic repayments and re-borrowings may be made until the maturity date.

Income Taxes [Abstract]
Income Taxes	NOTE 10 – INCOME TAXES In the preparation of the Company’s consolidated financial statements, management calculates income taxes based upon the estimated effective rate applicable to operating results for the full fiscal year. This includes estimating the current tax liability as well as assessing differences resulting from different treatment of items for tax and book accounting purposes. These differences result in deferred tax assets and liabilities, which are recorded on the balance sheet. These assets and liabilities are analyzed regularly and management assesses the likelihood that deferred tax assets will be recovered from future taxable income. In April 2016, we received notification from the Internal Revenue Service that they would be performing an examination of our 2012 and 2013 federal consolidated income tax returns. We do not expect that any settlement or payment that may result from the examination will have a material effect on our results of operations. At June 30, 2016 there was $ 227,000 of net uncertain tax benefit positions that would reduce the effective income tax rate if recognized. The Company records interest and penalties related to income taxes as income tax expense in the Condensed Consolidated Statements of Income.  The Company is subject to U.S. federal income tax as well as income tax of multiple state and foreign jurisdictions. The tax years 2012-2015 remain open to examination by the Internal Revenue Service and the years 2011-2015 remain open to examination by various state tax departments. The tax years from 2012-2015 remain open in Costa Rica. The Company’s effective income tax rate was (5.0%) for the first six months of 2016. The effective tax rate differs from the federal tax rate of 35 % due to state income taxes, foreign tax rate differences, foreign losses not deductible for U.S. income tax purposes, provisions for interest charges for uncertain income tax positions, and changes in valuation allowances related to deferred tax assets. The foreign operating losses may ultimately be deductible in the countries in which they occurred; however the Company has not recorded a deferred tax asset for these losses due to uncertainty regarding the eventual realization of the benefit. The effect of the foreign operations was an overall rate decrease of approximately (8.6%) for the six months ended June 30, 2016 . The Company's effective income tax rate for the six months ended June 30, 2015 was 30.0% , and differed from the federal tax rate due to state income taxes, foreign tax rate differences, foreign losses not deductible for U.S. income tax purposes and provisions for interest charges for uncertain income tax positions.

Net Income (Loss) Per Share [Abstract]
Net Income (Loss) Per Share	NOTE 13 – NET INCOME (LOSS) PER SHARE  Basic net income per common share is based on the weighted average number of common shares outstanding during each year. Diluted net income per common share takes into effect the dilutive effect of potential common shares outstanding. The Company’s only potential common shares outstanding are stock options and shares associated with the long-term incentive compensation plans, which resulted in no dilutive effect for the three and six-month periods ended June 30, 2016 . The Company calculates the dilutive effect of outstanding options using the treasury stock method. Due to the net losses in the first three and six-month periods of 2015, there was no dilutive impact from stock options or unvested shares. Options totaling 896,192 and 739,870 were excluded from the calculation of diluted earnings per share for the three and six-month periods ended June 30, 2016, respectively because the exercise price was greater than the average market price of common stock during the period and deferred stock awards totaling 159,689 shares would not have been included for the three and six-month periods ended June 30, 2016 because of unmet performance conditions. Options totaling 488,371 would have been excluded from the calculation of diluted earnings per share for the three and six-month periods ended June 30, 2015, because the exercise price was greater than the average market price of common stock during the period and deferred stock awards totaling 205,010 shares would not have been included for the three and six-months ended June 30, 2015 because of unmet performance conditions.

Fair Value Measurements [Abstract]
Fair Value Measurements	NOTE 14 – FAIR VALUE MEASUREMENTS The accounting guidance establishes a valuation hierarchy for disclosure of the inputs to valuation used to measure fair value. This hierarchy prioritizes the inputs into three broad levels as follows: Level 1 – Observable inputs that reflect unadjusted quoted prices for identical assets or liabilities in active markets that the Company has the ability to access at the measurement date. Level 2 – Observable inputs such as quoted prices for similar instruments and quoted prices in markets that are not active, and inputs that are directly observable or can be corroborated by observable market data. The types of assets and liabilities included in Level 2 are typically either comparable to actively traded securities or contracts, such as treasury securities with pricing interpolated from recent trades of similar securities, or priced with models using highly observable inputs, such as commodity options priced using observable forward prices and volatilities. Level 3 – Significant inputs to pricing that have little or no observability as of the reporting date. The types of assets and liabilities included in Level 3 are those with inputs requiring significant management judgment or estimation, such as the complex and subjective models and forecasts used to determine the fair value of financial instruments. Financial assets and liabilities measured at fair value as of June 30, 2016 and December 31, 2015 , are summarized below:     June 30, 2016   Level 1 Level 2 Level 3 Total Fair Value   Cash equivalents:  Money Market funds $ 2,255,000 $ - $ - $ 2,255,000  Certificates of deposit - -  Subtotal 2,255,000 - - 2,255,000   Short-term investments:  Certificates of deposit - 3,574,000 - 3,574,000  Corporate Notes/Bonds - 5,032,000 - 5,032,000  Subtotal - 8,606,000 - 8,606,000   Long-term investments:  Certificates of deposit - 1,450,000 - 1,450,000  Corporate Notes/Bonds - - - -  Subtotal - 1,450,000 - 1,450,000   Current Liabilities:  Contingent Consideration - - (122,000) (122,000)  Subtotal - - (122,000) (122,000)    Total $ 2,255,000 $ 10,056,000 $ (122,000) $ 12,189,000      December 31, 2015   Level 1 Level 2 Level 3 Total Fair Value   Cash equivalents:  Money Market funds $ 1,944,000 $ - $ - $ 1,944,000  Subtotal 1,944,000 - - 1,944,000   Short-term investments:  Certificates of deposit - 1,202,000 - 1,202,000  Corporate Notes/Bonds - 4,027,000 - 4,027,000  Subtotal - 5,229,000 - 5,229,000   Long-term investments:  Certificates of deposit - 4,286,000 - 4,286,000  Corporate Notes/Bonds - 2,007,000 - 2,007,000  Subtotal - 6,293,000 - 6,293,000   Current Liabilities:  Contingent Consideration - - (142,000) (142,000)  Subtotal - - (142,000) (142,000)   Total $ 1,944,000 $ 11,522,000 $ (142,000) $ 13,324,000  The estimated fair value of contingent consideration as of June 30, 2016 was $ 122,000 , as noted above. The estimated fair value is considered a level 3 measurement because the probability weighted discounted cash flow methodology used to estimate fair value includes the use of significant unobservable inputs, primarily the contractual contingent consideration revenue targets and assumed probabilities. The change in the estimated contingent consideration during the six months ended June 30, 2016 resulted in a gain of $ 20,000 included in operating income. The gains were the result of a change in future assumptions related to the contingent consideration..  We record transfers between levels of the fair value hierarchy, if necessary, at the end of the reporting period. There were no transfers between levels during the three months ended June 30, 2016 .

The estimates and assumptions used in the accompanying condensed consolidated financial statements are based upon management’s evaluation of the relevant facts and circumstances as of the time of the financial statements. Actual results could differ from those estimates.  Except to the extent updated or described below, the significant accounting policies set forth in Note 1 to the consolidated financial statements in the Company's Annual Report on Form 10-K for the year ended December 31, 2015 , appropriately represent, in all material respects, the current status of accounting policies, and are incorporated herein by reference.
