  In the above embodiment, transaction information is transmitted to the authentication server 60 every time a transaction occurs and authentication is performed. However, the transaction information is stored in the mobile phone 30 or the point card 40 for a certain period of time, for example, 1 You may authenticate by transmitting to the authentication server 60 the transaction information which concerns on the transaction performed for a fixed period collectively, such as transmitting every other day. As a result, the number of communications between the data management device 50 and the authentication server 60 can be reduced.

  In the above embodiment, one cash register 10 is connected to one data management device 50. However, a plurality of cash registers are connected to one data management device. Also good.

  In the above embodiment, when a transaction is performed, the transaction information and the point information of this time are transmitted again to the authentication server 60 as verification data at the time of the next transaction, but immediately after the current transaction. Even when the transaction information and the point information of this time are transmitted as verification data from the mobile phone 30 to the authentication server 60 by the consumer, the authentication server 60 validates the transaction related to the current transaction information and the point information. May be authenticated in real time. In this case, when the consumer makes a point inquiry from the mobile phone 30 to the point server 80 after authentication, the consumer can update the latest point without waiting for the next transaction. Further, when the current transaction information and point information are transmitted from the mobile phone 30 to the authentication server 60, the current transaction information stored in the mobile phone 30 is deleted, and the next transaction is performed at the next time. By transmitting only the transaction information and point information from the data management device 50 to the authentication server 60, the processing of the data management device 50 at the time of the next transaction is simplified.

  These modifications can also achieve the same effects as in the above embodiment.
