A shopping mall or a super market is a place where thousands of customers visit every day to purchase many products.Today purchasing various products in mallsor supermarkets require a trolley.Product procurement represents a complex process. Each time customer has to pull the trolley for getting the items and placing them in the trolley and also he has to take care of expense computation. After shopping the customer has to wait in a long queue for product scanning and bill payment. To overcome this we are developing a smart way for shopping. Each and every product contains RFID tag. The smart trolley will consists of a RFID reader, transmitter. When thecustomerscans and places any product in the trolley, cost and the name of the product will be displayed.The sum total cost of all the products will be added to the final bill, which will be stored in the micro controller memory. It will wirelessly transfer the product information of the items placed in the trolley using a transmitter to the main computer. So, to avoid waiting in billing queue while constantly thinking about the budget.
