Smart Shopping Trolley Using RFID

the purchasing various items in malls or supermarkets require a trolley. Product procurement represents a complex process. On each occasion customer items has to pull the trolley from rack to rack for collecting and simultaneously customer has to perform estimated expense computation. At the end, customer has to wait in queue for billing and payment. To overcome that we have been developed a smart way for shopping. Each and every product has RFID tag instead of barcode scanner. The smart trolley will consists of a RFID reader, LCD display and ZigBee transmitter. When a person puts any product in the trolley it will scan the product and the 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. This will be stored in the micro controller memory. It will wirelessly transfer the product information of the items placed in the trolley using a ZigBee transmitter to the main computer. So, to avoid waiting in billing queue while constantly thinking about the budget, a new concept has been introduced which is the “SMART-TROLLEY�.
