A cart consists of a handle, a basket and a set of wheels — we are going to leave all that but add some new features to make it contemporary and even more useful: A touch-screen. In the future all the things will have touch-screens; We build in a wi-fi adapter or its analog to wire all the carts into a LAN; We label all the products with tags that can be read remotely. We place a scanner inside the cart to identify whether a product item is inside the cart once we place it there.
