Abstract

A credit transaction processing system processes data related to a commodity entered into by using a card (17) owned by a customer and a recording card (16) owned by a store. First, merchant transaction data necessary for a credit sale stored in the recording medium (16), such as account number data for the store, data specifying a credit company, and data representing an upper limit of an amount to to be sold through a credit sale, are read by a card reader (5), and then, customer transaction data stored in the customer's recording card, such as account number data of the customer, data specifying a credit company and an identification number or code is read. If and when the customer enters his identification number by a ten-key (7), a central processing unit (12) determines whether the entered identification number coincides with the identification number read out of the customer's card. If and when a coincidence occurs, it is determined whether data indicating the purchase price of the commodity purchased by the customer is lower than the upper limit of the amount to be sold through a credit sale. If so, the price data is transmitted to a center station (3) and the amount of the money required for the credit sale is transferred from the bank account of the credit company utilized by the customer to the bank account of the store.
