    • 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.
    • 公开了一种商品结帐系统,其包括由客户操作的信用卡读卡器,以获得用于累积商品交易的信用信息。 结帐运营商利用数据终端来总计购买的物品的数量。 在数据终端的操作的同时,客户操作信用卡阅读器以读取由客户插入到读卡器中的信用卡,并且对该金额进行磁编码,即可以由 顾客。 如果可用金额大于所购商品的总金额,则从可用金额中扣除总金额,结果显示并打印在数据终端的收据和日记帐上作为支付金额。 如果可用金额小于所购买商品的总金额,则可从所购买商品总量中扣除可用金额,并将差额显示为客户要支付的应付金额以完成交易。
