Abstract
Each IC card 1 notifies a server 3 of the ID of the IC card and the connection information of a terminal device to which the IC card is connected. The server 3 stores the ID and the connection information in a database 4 while associating the ID and the connection information with each other. When an IC card 1 communicates with another IC card, the IC card 1 requests the connection information concerning the destination IC card from the server 3 while specifying the ID of this IC card. The server 3 searches the database 4 for the connection information corresponding to the ID specified by the request, and notifies the requesting IC card 1 of the acquired connection information. This enables communications between IC cards even if the terminal device to which a destination IC card is connected has been changed in the past.
