Abstract:

Now a days interest in shopping malls is widely increasing among people. People get daily necessities from shopping malls. There is an emerging demand for easy and quick payment of bills in shopping malls. Shoppers are frustrated at locating the items on he shopping list when shopping in shopping malls and when no assistance is available in shopping. To eliminate these problems, ch product in the shopping mall will be provided with a RFID tag, to identify its type. Each shopping cart is implemented with a ct Identification Device (PID) that contains a microcontroller, anLD, RFID reader and a ZIGBEE transmitter. RFID reader will readhe purchasing product information on the shopping cart and he information abut the product is displayed on LCD which is interfaced to the microcontroller. At the billing counter, the total bill will be transferred to PC at the counter side by using ZIGBEE module.In this paper , AT89S52 microcontroller is attached to an RFID reader and a barcode reader. As the user puts items in the trolley the reader on the trolley reads the tag and sends a signal to the controller. The controller then stores it in the memory and compares it with product ID. If it matches, it shows the name of item on LCD and also total amount of items purchased. Once the shopping is finished, the customer will press a button on the trolley send the total amount spent on the products to the billing counter section using ZIGBEE wireless communication module. In this project, there is a chance to revert back the product according to our need and budget. Once you take back product from the trolley, the same card will be again read by the RFID reader, then the controller will deduct the same amount associated to that product, from the net bill amount. The bill amount will be received by the ZIGBEE receiver and sent to the PC to display in the Hyper Terminal.
