The scale apparatus generates data signals representing the weight of the merchandise item which are then transmitted to a processor means which also receives data signals from the scanning unit identifying the merchandise item. The processor means will generate the price of the merchandise item using the data signals received. The price of the merchandise item is then displayed on a display unit and printed by a printing unit on a customer's receipt.
