POINT-OF-SALE TERMINAL ADAPTED TO PROVIDE PRICING INFORMATION FOR SELECTED PRODUCTS

摘要

The present invention relates to a method for using a point-of-sale terminal to provide promotional messages during the checkout of products. The first step involves scanning, via scanner (15), a machine-readable code on a product to be purchased and generating a signal representing said code on the product to be purchased. This signal is then used to retrieve the price of the product from a first memory (19). This signal is also used to identify a product which is equivalent to the product to be purchased and to retrieve the price of the equivalent product from a second memory (14). The price retrieved from the second memory (14) is then subtracted from the price retrieved from the first memory (19) to derive a price difference. Finally, the price difference is displayed on a display means (17). This price difference may then be used by a consumer to decide if the equivalent product is a better value than the product he intended to purchase.
