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 defining three-dimensional acceptance clusters, the data for which are stored in look-up tables in memory associated with a microprocessor. A second aspect involves fraud prevention by temporarily tightening or readjusting item acceptance criteria when a potential fraud attempt is detected. A third aspect relates to minimizing the effects of counterfeit items such as slugs on the self-adjustment process for the item acceptance criteria. A final aspect relates to the calculation of a relative value of the acceptance criteria in order to conserve memory space and minimize computation time. <IMAGE> |
