SMART, TELEPHONE COMPRISING SUCH A CARD AND METHOD FOR EXECUTING A COMMAND IN SUCH A CARD

摘要

A smartcard (1) includes:a first and a second microprocessor (110, 210),elements for receiving (14) commands each coming from a first or a second communications channel external to the card (1) and for transmitting the received commands to the first microprocessor, characterized in that the first microprocessor includes elements for determining (706) whether a received command has been received on the second communications channel so as to transmit (708) the received command to the second microprocessor (210) in the case of a positive determination. Notably, the determination can be carried out by detecting an electrical contact of the communications interface of the card, over which the command is received. Application of the invention to a card having a second microprocessor for executing a highly securitized application, of the banking transaction type, and a first less securitized application, of the mobile telephony application type.
