Smart Cart

  A shopping cart with a UPC code reader attached so you scan your grocery purchases as you put them in the cart, when you get to the check out line you already know how much you owe, your cart is placed on a scale, and checked against the expected weight of the items you scanned, the total is confirmed and you're on your way.
