Transaction processing system and transaction processing method

Abstract

In accordance with an embodiment, a transaction processing system includes a user terminal, an authentication server, a payment server, and a receipt server. The receipt server manages receipt information regarding a transaction paid for by the payment server in association with a user's identifier acquired by the authentication server on the basis of biometric data input by the user terminal.

What is claimed is: 
     
         1 . A transaction processing system that provides a transaction processing service to a user, comprising:
 a user terminal that inputs biometric data of a user who performs payment of a transaction as a target of the transaction processing service;   an authentication server that authenticates the biometric data input by the user terminal, and acquires an identifier for identifying the user who performs the payment in a case where the authentication has succeeded, the identifier being associated with the biometric data;   a payment server that acquires payment data associated with the identifier acquired by the authentication server and pays for the transaction by using the acquired payment data; and   a receipt server that manages receipt information regarding the transaction paid for by the payment server in association with the identifier acquired by the authentication server.   
     
     
         2 . The transaction processing system according to  claim 1 , further comprising
 a reward server that gives a reward related to the transaction paid for by the payment server to the user associated with the identifier acquired by the authentication server.   
     
     
         3 . A transaction processing system that provides a transaction processing service to a user, comprising:
 a user terminal that inputs biometric data of a user who performs payment of a transaction as a target of the transaction processing service;   an authentication server that authenticates the biometric data input by the user terminal, and acquires a first identifier for identifying the user who performs the payment in a case where the authentication has succeeded, the identifier being associated with the biometric data;   a payment server that acquires payment data associated with the first identifier acquired by the authentication server and pays for the transaction by using the acquired payment data;   an agency server that converts a first identifier acquired by the authentication server to obtain a second identifier for identifying a receipt regarding the transaction; and   a receipt server that manages receipt information regarding the transaction paid for by the payment server in association with the second identifier obtained by conversion by the agency server.   
     
     
         4 . The transaction processing system according to  claim 3 , further comprising
 a reward server that gives a reward related to the transaction paid for by the payment server to the user associated with the second identifier obtained by the conversion.   
     
     
         5 . The transaction processing system according to  claim 4 , wherein
 the agency server converts the first identifier acquired by the authentication server to obtain each of a second identifier for the receipt and a second identifier for the reward.   
     
     
         6 . The transaction processing system according to  claim 5 , wherein
 the receipt server uses the second identifier for the receipt obtained by the agency server to manage the receipt information regarding the transaction paid for by the payment server.   
     
     
         7 . The transaction processing system according to  claim 5 , wherein
 the reward server uses the second identifier for the reward obtained by the agency server to give the reward related to the transaction paid for by the payment server to the user.   
     
     
         8 . A transaction processing method for a transaction processing system that provides a transaction processing service to a user, comprising:
 inputting, by a user terminal, biometric data of a user who performs payment of a transaction as a target of the transaction processing service;   authenticating, by an authentication server, the biometric data input by the user terminal, and acquiring an identifier for identifying the user who performs the payment in a case where the authentication has succeeded, the identifier being associated with the biometric data;   acquiring, by a payment server, payment data associated with the identifier acquired by the authentication server and paying for the transaction by using the acquired payment data; and   managing, by a receipt server, receipt information regarding the transaction paid for by the payment server in association with the identifier acquired by the authentication server.   
     
     
         9 . The transaction processing method according to  claim 8 , further comprising
 giving, by a reward server, a reward related to the transaction paid for by the payment server to the user associated with the identifier acquired by the authentication server.   
     
     
         10 . The transaction processing method according to  claim 8 , further comprising
 converting, by an agency server, an identifier for identifying the user who performs the payment acquired by the authentication server to obtain an identifier for identifying a receipt regarding the transaction, wherein   the step of managing, by the receipt server, the receipt information regarding the transaction paid for by the payment server includes managing the receipt information in association with the identifier for identifying the receipt related to the transaction acquired by the authentication server.
