Abstract
The use of chip cards, with the level of security of the type associated with chip cards of the type used by banks, is extended to move widespread use by organizing a secure dispatch of blank chip cards to customers wishing to program specific applications therein. The system consists in sending this customer the blank chip card itself and a programming access key to this card, by separate routes. To prevent any additional risks, the access key is itself enciphered and can be deciphered only be a deciphering element in the possession of the customer. The card can then be programmed only if this card is confronted with its deciphering key.
