Electronic payment method for automatic service equipment and electronic payment system for automatic service equipment

摘要

PROBLEM TO BE SOLVED: To provide an electronic payment method and a system of a highly safe and inexpensive automatic service device. SOLUTION: A user logs in to an electronic payment brand 130 by a beneficiary terminal 126 and receives a one-time token 1TT. The one-time token 1TT displayed on the display device of the beneficiary terminal 126 by the QR code (registered trademark) QRC is imaged by the image pickup device 150 of the device terminal 110 and transmitted to the store server 114. The store server 114 generates the transaction number TNO and transmits it to the payment server 124 via the payment GW server 118. When the one-time token 1TT has the legitimate authority, the settlement server 124 performs the settlement processing SET and transmits the settlement result information SEI to the store server 114 via the settlement GW server 118. If the time from the issuance of the transaction number TNO to the reception of the settlement result information SEI exceeds a predetermined time, the store server 114 invalidates the settlement process as a time over.
