The system includes four main functional components: a plurality of cards (10), a host computer (12), a plurality of on-site activation terminals (14) and a main processor (16). Each of the cards (10) has a security number associated therewith. The card (10) is typically formed of cardboard, paper or plastic and may include the security number in cleartext under a suitable blackout. The main management and processing of the system is effected by the host computer (12). The host (12) includes a database for storing security numbers associated with authorized cards (10). The data terminals (14) are remote from the host computer (12) and connectable thereto for transmitting data between the terminals (14) and the host computer (12). The processor is controlled by the host computer (12) for enabling customer purchases using the authorized cards (10).</p> |
