CA 2268115

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.

Cette invention concerne un procédé et un système permettant d'empêcher l'utilisation frauduleuse de cartes de crédit électroniques et intelligentes (11) qui utilisent des micropuces afin de stocker une certaine somme d'argent. Ces cartes ont pu récemment être utilisées de manière frauduleuse grâce à des techniques électroniques permettant de briser les codes de sécurité. Afin d'éviter ce genre d'utilisation frauduleuse, on colle (fig. 3) une bande de mémoire optique (17, 41, 74) sur la carte intelligente, des données de validation (19) étant enregistrées préalablement ou ultérieurement sur les cartes (fig. 1). Ces données de validation optiques sont lues (fig. 2) par un réseau de photodétecteurs (65), puis transmises au destinataire lors d'un transfert de fonds et/ou utilisées localement afin de gérer la distribution d'argent liquide. Toute utilisation frauduleuse de la carte de crédit électronique modifiée ne peut ainsi se faire qu'en répondant exactement aux conditions électroniques et optiques.
