Barcode Scanners

Technology has come a long way since I was a little girl. I remember when I would go shopping with my mom and it came time to check out the gal at the register had to push buttons to add in the cost of the items. Now if you walk into a store and go to the check out lanes everyone is using barcode scanners. Many of them are wireless so that if you have a large item they can just come over to your cart and scan it. It's pretty cool how it all works.
