This little machine acts like an optical scanner at a store where you scan and pay for your items. You can scan your LEGO motors, wheels, red ball, and a few small items representing cakes, veggies, and a fork. When you're done shopping, scan your black and yellow "credit card" and the scanner will display a list of all of the items you scanned and a total price.
