The U-Scan Shopper is a ruggedized XScale-based wireless computer with an integral bar code scanner, running Windows CE 4.2, and mounted on a shopping cart. The company even suggests that customers might upload a shopping list to the store's website before leaving home, and then download the list to the shopping cart upon arriving at the store."
