The value entity receiver 21 receives a value entity 11a accompanied by a public key A1 corresponding to a private key A2, and the value entity 11a received is stored into a value entity storage 22. The application receiver 23 receives an application 31a electronically signed by the private key A2, via an ad hoc network N2. The application verifier 24 verifies the application 31a through the use of the public key A1, and when the application is successfully verified, the value entity transmitter 27 transmits (or transfers) the value entity 11a to a store server 30 through the use of the application 31a.
