<P>PROBLEM TO BE SOLVED: To provide an IC card which can change a command process in response to the communication I/F by which the IC card is operated even when it executes the same command. <P>SOLUTION: The IC card 1 is provided with a read command 4 as a command. The command 4 is owned in a transmission control program 3, and the command 4 refers to the communication I/F information 32 by which the IC card 1 is operated, and selects to execute a first processing means 40 or a second processing means 41. When the IC card 1 operates through a contact I/F, the first processing means 40 reads out a first public key certificate 50, and a transmission control program 3 transmits a response message including the first certificate 50 to a not shown terminal device. When the IC card 1 operates through a non-contact I/F, a second processing means 41 reads out a second public key certificate 51, and the program 3 transmits a response message including the second certificate 51 to the not shown terminal device. <P>COPYRIGHT: (C)2007,JPO&INPIT |
