In today’s life going to supermarkets for shopping is increasing rapidly. People take the item and put it into trolley. After done with shopping they go for billing at the Billing counter but as there are many people standing in Queue for billing purpose, So lots of time is required for the individuals for billing because of existing barcode technology. To reduce this time we are proposed a system based on RFID technology. The system contains the items attached with RFID tag, RFID reader which reads the tag information when put into the trolley. Then this information is send to main billing server which calculates the total amount of purchased items and sends the calculated bill to the device attached to trolley for displaying it on LCD. Along with this system we are implementing an Android application for controlling the trolley movements. The application is based on the Trolley number and total amount of purchased items.
