<p>A self-adhesive product label (10) is printed with a code 128 bar code (12) and an EAN bar code (14). The code 128 bar code (12) is adapted to be read by hand-held scanners and includes information concerning the price indicated on the label. The EAN bar code (14) can be read by a conventional scanner but not by the hand-held scanner. When it is desired to reduce the price of a product the label (10) with two bar codes is printed. A hand-held scanner will read the code 128 bar code (12) (including the reduced price). In contrast, if the product is scanned conventionally with a static scanner by an assistant it will only respond to the EAN bar code (14), thereby alerting an assistant to the fact that the product is to be sold at a reduced price. The label also preferably carries the reduced price (18). <IMAGE></p> |
