long line at register

It baffles me how we can place barcodes on products, yet we cant build a gateway you walk the shopping cart through, to auto scan every item and simply give you a total price. This would enable you to:

Pack your groceries as you shop, and not need to repack and unpack them in the checkout line

No need to hire people to work the checkout register

harder to steal products by sneaking them past checkout operators eyesight if scan methodology improves
