management server that manages the card and for writing information transmitted fromthe management server to the card, a server state flag and a card state flag are createdto indicate the processing state of the management server and the processing state ofthe card, respectively. The server state flag and the card state flag are occasionallyupdated during communication between the card and the management server.
