    • A system and method to adapt a fuel dispenser and related facilities to accept bar coded cards in addition to or instead of magnetic strip cards. A standard bar code reader is used in conjunction with a magnetic strip card reader. The bar code reader includes a light detector and a light source. The light detector and light source are secured so that they may visually access a card in the magnetic strip card reader. This allows the light detector to access bar coded data that is printed on a bar coded card. Furthermore, the addition of the bar code reader does not prevent the magnetic strip card reader from also reading a magnetic strip if it is present on the card. When a bar coded card is slid into the magnetic strip card reader, the bar code reader interprets the signals generated thereby and "decodes" the signals into corresponding numbers. These numbers are then sent over a data bus to a controller, where they are interpreted. Once interpreted, the numbers can be used similarly to numbers conventionally produced by a magnetic strip card, or can be used separately to provide additional services and/or advantages, such as updating a frequent purchase account.
    • 一种用于使燃料分配器和相关设施适应于除了磁条卡之外或代替磁条卡接受条形码卡的系统和方法。 标准条形码读取器与磁条读卡器一起使用。 条形码读取器包括光检测器和光源。 光检测器和光源被固定,使得它们可视觉地访问磁条读卡器中的卡。 这允许光检测器访问打印在条形码卡上的条形码数据。 此外,如果条形码读取器存在于卡上,则附加的条形码读取器不会阻止磁条读卡器也读取磁条。 当条形码卡被滑入磁条读卡器时,条形码阅读器解释由此产生的信号并将信号“解码”成相应的数字。 然后,这些数字通过数据总线发送到控制器,在那里它们被解释。 一旦被解释,这些数字可以类似于通过磁带卡产生的数字使用,或者可以单独使用以提供额外的服务和/或优点,例如更新频繁购买帐户。
