Wireless Intelligent Billing Trolley for Malls

Microcontroller based design, has acquired the status of most happening field in electronics. This is highly specialized field that has the power of integrating thousands of transistors on single silicon chip. Nowadays, in mall for purchasing variety of items it requires trolley.As we know that there is a huge crowd in the malls in metro cities. Specially it becomes more crowded on holidays. People purchase different items in the malls and puts them in the trolley. At the cash counter billing process is done using bar code scanner. This is very time consuming process. To avoid this we are developing a system which we call as Wireless Intelligent Billing Trolley for Malls. In this system we are using RFID tags instead of barcodes. This RFID tags will be on the product. Whenever the customer puts a product into trolley it will get scanned by bvgfc RFID reader and product price and cost will be display on LCD display. Like this the process goes on. We are using ZIGBEE transmitter which will be at trolley which is used to transfer data to main computer. At the main computer ZIGBEE receiver will be placed which will receive data from transmitter. The heart of circuit is an ARM7 (LPC2148), which is of NXP semiconductor (Philips) made IC. LCD used will be 16X2 alphanumeric display . It will be used to display products names, products cost etc.
