Price Look Up

This stands for price look up. PLU codes are 4 or 5-digit numbers which have been used by supermarkets since 1990 to make check-out and inventory control easier, more efficient, and more accurate. It’s an effective system that displays the description and price of an item when the item number is entered or scanned at the point of sale. They ensure that the correct price is paid by consumers by removing the need for cashiers to attempt to identify the product.
