CREDIT CARD RECOMMENDING METHOD, PROGRAM AND DEVICE

摘要

A member registering section registers information on credit cards possessed by a customer and issues a member card to the customer. A card judging section searches for a user credit card by using the card information on the member card as a key with reference to credit card information and service information on the credit cards contained in the database of a shop server and judges from the search result whether use of which card is the greatest advantage to the customer. A card displaying section displays the credit card judged to yield the greatest advantage or displays the credit cards in order of advantage.
