So Rachel and I went clothes shopping today at GU, a store similar to Old Navy and the checkout system was one we have never experienced. (We have used the Checkout system at Walmart before.) You put your cart or items below in the drawer and the machine scans the barcodes on your items. Then it is much like an ATM system where you put your money in or swipe your credit card. After paying, you bag your items behind you. Technology at its best- there was even an English button!
