Abstract

A merchandise checkout system is disclosed including a credit card reader operated by the customer to obtain credit information used in totalizing the merchandise transaction. A data terminal is utilized by the checkout operator to total the amount of the purchased items. Simultaneously with the operation of the data terminal, the customer operates the credit card reader to read a credit card inserted into the card reader by the customer and on which is magnetically encoded the amount of money, i.e. balance of account, available for use by the customer. If the amount available is greater than the total amount of the purchased items, the total amount is subtracted from the available amount with the result displayed and printed on the receipt and journal records of the data terminal as the amount paid. If the available amount is less than the total amount of the purchased items, the amount available is subtracted from such total of purchased items and the difference displayed as the amount due which is to be paid by the customer to complete the transaction.
