摘要

The objective of the present invention is to lighten the burden of management for credit card information at seller-side without affecting convenience in transactions using a credit card for both a customer and a seller. On the basis of actual data for a credit card, a virtual mall server (3) and a credit card server (5) share conversion information for acquiring dummy data for a corresponding credit card. The virtual mall server (3), on the basis of the conversion information, acquires the corresponding dummy data on the basis of the actual data for the credit card used in settlement of order information, whereupon the acquired dummy data is transmitted to the store terminal as data for the credit card used in the settlement of the order information. The credit card server (5), upon receiving a predetermined card processing request based on the dummy data from the store terminal, acquires the actual data for the corresponding credit card on the basis of the dummy data according to the conversion information so that, on the basis of the actual data for the acquired credit card, the predetermined card processing is executed.
