METHOD AND APPARATUS FOR IMPROVED COIN, BILL AND OTHER CURRENCY ACCEPTANCE AND SLUG OR COUNTERFEIT REJECTION |
摘要 |
Methods and validation apparatus for achieving improved acceptance and rejection for coins, bills and other currency items. One aspect includes modifying item acceptance criteria by creating and de fining three-dimensional acceptance clusters (CA, CB, CC), the data for which are stored in look-up tables in memory associat ed with a microprocessor (35). A second aspect involves fraud prevention by temporarily tightening or readjusting item a cceptance criteria when a potential fraud attempt is detected. A third aspect relates to minimizing the effects of counte rfeit items such as slugs on the self-adjustment process for the item acceptance criteria. A final aspect relates to calculation of a relative value of the acceptance criteria in order to conserve memory space and minimize computation time. |
