A self-service checkout station allows a purchaser to scan coded labels on each merchandise item purchased and to generate the weight of the items at a first checkout counter. The weight of each merchandise item is compared with corresponding data stored in a remote memory member. If the weight of the item is found to be valid, the combined weight of the purchased merchandise items is then determined. The purchaser takes the purchased merchandise items to a second checkout counter where the combined weight of the merchandise items is again generated and compared with the previous generated combined weight. If the combined weights are found to be valid, the checkout operation is completed. A display member at the first checkout counter informs the purchaser of the price of each merchandise item being processed while a second display member at the second checkout counter displays the total amount due for the purchased merchandise items. |
