Smart cart technology allows consumers to e-mail their shopping lists to the store. At the store, all shoppers do is grab a smart cart and swipes a customer loyalty card across a reader to activate it. The cart, which also features a touch-screen display, immediately attunes itself to the consumer, displaying his or her shopping list and showing a map indicating where desired items are located. The cart also offers instant discounts on some products, and suggests other things the consumer might want or need.
