Conventional supermarket checkout systems generally require products to be identified and billed at a designated point-of-sale counter. During busy shopping periods, customers may need to wait for checkout and may not have a convenient way to monitor the total cost while selecting products. A smart shopping trolley can move some product-recording and billcalculation tasks closer to the shopper. Earlier smart-cart research has explored automatic billing, product information and antitheft functions using RFID and wireless communication [1].
