To eliminate the need of calculation by a user by selecting the payment destination bearing of a payment charge when the payment charge is payment destination bearing and automatically calculating a final payment amount which is to be actually paid.

When payment destination information is inputted after payment transaction is selected, a payment charge selection screen is displayed on a display device with a touch panel 10. The user selects and designates whether the payment charge is borne by a payment source or the payment destination. Payment destination bearing is designated and the payment amount (whole amount required for payment) is inputted, for example. Then, the name of a paying person and the telephone number of the paying person are sequentially inputted. Thus, a main control part 21 obtains the payment charge from the amount required for payment, which is previously inputted, subtracts the charge from the amount required for payment, obtains the final payment amount, and displays the final recognition screen of the payment charge and the payment amount. The user supplies cash equivalent to the payment amount and therefore money reception processing/payment transaction processing are executed.
