A means (SS, CT) external to a terminal (TM) transmits a specific application identifier and first encrypted key and number to a first smart card (CA) in use in the terminal. In the first card, when the first decrypted number satisfies a first condition, the specific application is invoked, the data of the application are read, the data are encrypted while using the first decrypted key for transmitting them to the external means, and the application is then rendered inoperable. After replacing the first card with a second card (CB), the external means transmits the identifier and the second encrypted key and number to the second card. When the second decrypted number satisfies a second condition, the encrypted data are transmitted to the second card so that this card invokes the application, decrypts the encrypted data while using the second decrypted key, and installs this data. |
