This application simplifies the name of the member stores of this application when entering the store by using the transportation IC card or distribution IC card that the customer has.These IC cards are called non-contact IC cards and have only one unique number in the world. It is troublesome to register the name at every store or event venue where customers enter or enter, and it is hesitant to leave personal information in various places. The management side also wants to avoid keeping personal information in terms of management.Therefore, as a solution, this application has a mechanism to memorize only the unique number and date and time with anonymity instead of the signature just by scanning the non-contact IC card. In accordance with the privacy policy, the shop cannot collect personal information without the consent of the customer even if it is necessary to contact in an emergency.If personal information is required, the store or event operator will obtain the consent of the customer in advance.
