摘要

A seller's workload of managing credit card information can be reduced without changing convenience for an orderer and the seller in a transaction using a credit card. A virtual mall server (3) and a credit card server (5) share conversion information for obtaining, from actual data of the credit card, corresponding dummy data of the credit card. The virtual mall server (3) obtains, based on the conversion information, the corresponding dummy data from the actual data of the credit card to be used for a settlement of the order information, and sends the obtained dummy data to a shop terminal as data of the credit card to be used for the settlement of the order information. Upon receiving, from the shop terminal, a predetermined card processing request based on the dummy data, the credit card server (5) obtains, based on the conversion information, the corresponding actual data from the dummy data of the credit card, and performs the predetermined card processing based on the obtained actual data of the credit card.
