Abstract: A system includes a server apparatus and an authentication terminal. The server apparatus stores biometric information of at least one or more users who plan to use a hotel. The authentication terminal is managed by an affiliated business operator that has a partnership relationship with the hotel and transmits an authentication request that includes biometric information of a person to be authenticated to the server apparatus. The server apparatus identifies the person to be authenticated among the at least one or more users by a matching processing using the biometric information included in the authentication request and the stored biometric information. When the identified person to be authenticated is a hotel user who uses or has used the hotel within a predetermined period of time based on a time of processing the authentication request, the server apparatus provides the hotel user with a reward related to the affiliated business operator.

Abstract: A system includes server apparatus and business operator terminal. The server apparatus stores biometric information of users who plan to use a hotel. The authentication terminal transmits user behavior notification that includes biometric information and behavior information of person to be determined to the server apparatus. The server apparatus identifies the person to be determined among the users by matching processing. The server apparatus determines whether the identified person to be determined is hotel user who will use the hotel or who used the hotel based on time of processing of the user behavior notification. The server apparatus determines whether the identified person to be determined is target person to be rewarded based on the behavior information. When the person to be determined is the hotel user and the target person to be rewarded, the server apparatus provides the person to be determined with a reward related to the hotel.
