ABSTRACT:
A purchase monitoring device, to be used by a shopper in a self-service store having items with bar codes which identify the item and its price, the device including primarily a portable handset having a bar code scanner which enables pricing and identification data of a selected item to be displayed on an LED display of the handset. Through selective use of a price check button, a purchase button, and a return button, the price of the item may be checked, added to a running total of purchase items, or removed from a running total of purchased items. During scanning of an item, a three headed roller selectively designates the item as a purchase item or as a non-purchase item by marking the bar code with either a red or a green line, so the purchase items can be quickly verified. Alternatively, the roller may change the state of a polarized metallic strip included with the bar code. The list of purchase items is stored within the handset for subsequent transfer to a data reception register of the store for payment.
