I know all of you shop in the big high tech stores. You've seen these stores using computerized systems to make their jobs faster and convenient both for consumers and employees. Not only that, the items we buy from those stores have bar codes for tracking sales and inventory. Also the wedding and baby registry systems use barcode scanners to help you find the price of the item you want to buy at their stores. These scanners help to make the transactions of both parties so much quicker.
