<p>A method and system for inhibiting the counterfeiting of electronic cash smart cards (11) that use microchips for monetary stored value. Such cards have recently been counterfeited by the use of electronic techniques to break the security codes. Such counterfeiting can be inhibited by bonding (Fig. 3) an optical memory stripe (17; 41; 74) to the smart card with pre-recorded or post-recorded validation data (19) on the cards (Fig. 1). This optical validation data would be read (Fig. 2) with a photodetector array (65) and could be transmitted to the recipient during funds transfer and/or used locally to control dispensing of cash. Thus, successful counterfeiting of the modified electronic cash card would require meeting exacting electronic and optical requirements.</p> |
