A biometrics authentication system uses biometrics authentication media to simplify the process of issuing biometrics authentication media, and reduce issuing costs. A biometrics authentication application is downloaded from a server to a mobile communication terminal, and an area for authenticated biometrics information is created. A user brings this mobile communication terminal to a service area and causes an image of his own biometrics information to be captured, and this biometrics data and an account number are stored in a common area of the mobile communication terminal. Therefore, the mobile communication terminal has functions of an individual card storing biometrics information, and issuing of a card for use in biometrics authentication is completed.
