An IC card 16 according to the present invention is provided with an
electronic value storing means, a request acquiring means, a verifying
means, and an output means. The request acquiring means acquires an
access request from display application 151 to electronic value 161
stored in the electronic value storing means, along with application
authentication information held by the display application 151. The

acquiring means. When the verifying means determines that the application
authentication information is valid, the output means outputs substantive
information of the electronic value 161 to the display application 151.
