<P>PROBLEM TO BE SOLVED: To enable communication using a plurality of external interfaces 25, 26 in parallel and to perform a plurality of processes in parallel in a manner that matches the communication at the plurality of external interfaces 25, 26. <P>SOLUTION: An IC card 10 having a plurality of external interfaces 25, 26 is so formed that if, when a request to start communication at one of the external interfaces 25 (26) is received, the other of the external interfaces 26 (25) is in communication, a process matching the communication at the external interface 25 (26) that has received the request to start communication is performed on a logical channel different from a logical channel where a process matching the communication at the external interface 26 (25) in communication is performed. <P>COPYRIGHT: (C)2008,JPO&INPIT |
