<p>The present invention is a system including a card (5); an antenna (8) to receive information to be written onto the card, preferably a Mifare antenna; a processor (9) connected to the antenna (8) which is entirely independent from the validator or POS processor; the validator or POS processor; and one or more SAM storage modules (10) which contain the tables, access codes and other sensitive information. The SAM module is also controlled by the system administrator which allows dynamic and diversified codes to guarantee the security and veracity of the information being transmitted. The system is capable of being programmed regardless of the POS processor. The sensitive data can be withheld entirely from the suppliers of the antenna and POS processor technology. Additionally, because each antenna has its own processor, it can work both on-line and off-line. The processor (9) also has a non-volatile EEPROM memory (11) for information storage, but stores the access codes in volatile memory so that power loss will erase the access codes from the processor memory, leaving them only in the storage module memory. All of these features restrict access to sensitive system information and secure that information from outside suppliers.</p> |
