ABSTRACT:
An electronic money usage system is capable of preventing dishonest use of electronic money recorded on a recording medium. A memory card300acquires signature-type electronic data from a bank server apparatus100, and generates a first authenticator using the received first authenticator, and an identification flag, an electronic money ID and an amount included in the electronic money. When a user uses the signature-type electronic money, the memory card300generates a second authenticator with use of a second password received from the user, and the identification flag, electronic money ID and amount included in the electronic money. The memory card300outputs the electronic money if the first authenticator and the second authenticator match.
