PURPOSE: A card payment method is provided to process a card payment with only a secret number without a customer's signature on a printed sale slip and to transfer the payment amount to an account of an affiliated store as soon as the card is normally approved. CONSTITUTION: An affiliated store selects a card payment menu at a payment processing terminal(700), and the payment processing terminal requests an access to a server of a service provider(710). The server of the service provider approves the access request from the payment processing terminal(720). The payment processing terminal reads the data on the card of a customer if it is inserted into a slot of the terminal(730), and receives a secret number of the card and the payment amount(740, 750). The terminal transmits the card data, the secret number and the payment amount to the server of the service provider(760), and then the server of the service provider transmits the received data and the data on the affiliated store to a server of a card company for requesting a transaction approval(780). The server of the card company checks the credit of the customer(790), transmits the check result to the server of the service provider(800). If the credit of the customer is normal, the server of the card company instantly transfers the payment amount to the account of the affiliated store(850). The card processing terminal receives the credit check result(810) and displays it(820).
