Abstract
The invention concerns a microcircuit card comprising means (RX) for receiving a command and means for modifying at least one performance of the card capable of being implemented after a step of personalization of the card.
Claims19
A microcircuit card (100) comprising:
- a receiver means (RX) for receiving a command (200);
- means for modifying at least one characteristic of the performance of said card on reception of said command, the modification means being characterized in that they can be used after a step (E10) of personalization of said card;
- and
- cryptographic means for authenticating the sender of said command,
- wherein said receiver means (RX) are configured to receive said command (200) in accordance with an SMS type protocol.
2 more elements
A method of configuring a microcircuit card (100) comprising the steps of:
- personalizing (E10) said card;
- receiving (E20) a command (200);
- cryptographically authenticating the sender of said command;
- and
- modifying (E40, E60, E70, E80) at least one characteristic of the performance of the card on reception of said command (200),
- wherein said receiving step (E20) receives the command in accordance with an SMS type protocol.
