Abstract
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 verifying means determines the validity of the application authentication information in accordance with the access request acquired by the request 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.
