A secure element (SE) unit 102 holding service data used by an application is provided in a UIM card 100. Thus, when the user identify module (UIM) card 100 is transferred between portable terminals, service data and accompanying information of the application can be moved together with the UIM card 100 to another portable terminal. In addition, an access management unit 400 included in a portable terminal 200 compares UIM information of a UIM information storage unit 103 with UIM information, held by an authority information holding unit 205, of a UIM card of which use authority is possessed by an application. If they do not agree, access to service data stored in the SE unit 102 is restricted.
