    Abstract: A point management system (10) manages first points required for receiving a first service. The first points are managed for each group to which a plurality of persons belong. A second apparatus (30) acquires service determination information for determining the type of the first service provided to a user being one of the plurality of persons. A first apparatus (20) determines the number of required points being the number of first points required for the first service by using the service determination information. The second apparatus (30) performs processing for providing the first service to the user. Further, the second apparatus (30) reduces the first points by the number of required points.

    Abstract: An authentication terminal includes a first acquisition unit, a second acquisition unit, a control unit, and an authentication processing unit. The first acquisition unit acquires first biometric information of a user from another apparatus when a distance between own terminal and the user reaches a first distance. The second acquisition unit acquires second biometric information of the user when the distance between own terminal and the user reaches a second distance. The control unit performs control to acquire data for authentication from a terminal possessed by the user, which is necessary to determine whether or not to provide a service to the user. The authentication processing unit determines that an authentication processing of the user is successful when a result of the matching processing using the first biometric information and the second biometric information is successful and the data for authentication acquired from the terminal is valid.
