Abstract:
1. An IC card that is coupled to a portable terminal device, the IC card comprising: a first interface which performs communication with the portable terminal device; a second interface which performs contactless communication with an external device by using a contactless communication unit of the portable terminal device; a storage unit which stores a plurality of application programs that execute processing during the contactless communication; a holding unit which holds an application list including setting information for each application program, wherein the setting information has an initial value indicating whether disclosure responsive to an access request via the second interface is permitted, the initial value being set to inhibit disclosure; an updating unit which updates the setting information of an application program to be permitted to be disclosed in response to a setting change request received from the portable terminal device via the first interface, the setting change request including information indicating that the application program is permitted to be disclosed; and a processing unit which responds to the information of the setting change request indicating that an application program is permitted to be disclosed, by enabling disclosure of the application program via the second interface, wherein in response to the access request through the contactless communication, permitted applications from the application list are automatically transmitted to the external device.
