© ALM AYMIS UNIT, SEUSL9 The structure of the card number varies by system. For example, American Express card numbers start with 37; Carte Blanche and Diners Club with 38. ◦American Express - Digits three and four are type and currency, digits five through 11 are the account number, digits 12 through 14 are the card number within the account and digit 15 is a check digit. ◦Visa - Digits two through six are the bank number, digits seven through 12 or seven through 15 are the account number and digit 13 or 16 is a check digit. ◦MasterCard - Digits two and three, two through four, two through five or two through six are the bank number (depending on whether digit two is a 1, 2, 3 or other). The digits after the bank number up through digit 15 are the account number, and digit 16 is a check digit.

© ALM AYMIS UNIT, SEUSL10 Smart Cards The "smart" credit card is an innovative application that involves all aspects of cryptography (secret codes), not just the authentication. A smart card has a microprocessor built into the card itself. Cryptography is essential to the functioning of these cards in several ways: The user must corroborate his identity to the card each time a transaction is made, in much the same way that a PIN is used with an ATM. The card and the card reader execute a sequence of encrypted sign/countersign-like exchanges to verify that each is dealing with a legitimate counterpart. Once this has been established, the transaction itself is carried out in encrypted form to prevent anyone, including the cardholder or the merchant whose card reader is involved, from "eavesdropping" on the exchange and later impersonating either party to defraud the system.
