authenticating a person as, for example, the user himself/herself. That is to say,
biometric authentication is performed. In addition, functions like an electronic
purse a conventional IC card etc. had are included in the portable communication
terminal device (portable personal authentication apparatus) and the portable communication
terminal device is connected to ATM equipment etc. This enables the portable communication
terminal device to be managed unitarily as an electronic purse. Furthermore, a
portable communication terminal device (portable personal authentication apparatus)
is used for authenticating a person as, for example, the driver himself/herself
