Purchasing and Shopping at big malls is becoming daily activity in metro cities. We can see big rush at these malls on holidays and weekends. This crowd becomes huge when there are special offers and discount. People purchase different items and put them in trolley. After total purchase one need to go to billing counter for payments. At billing counter the cashier prepare the bill using bar code reader which is very time consuming process and results in long queue at billing counter.
Our aim is to develop the system which can be used in shopping malls to solve the problem mentioned above. The system will be placed on trolleys in the mall. It will consist of RFID reader. All the items in the mall will be equipped with RFID tags. When person put any item in the trolley its code will be detected and the price of that item will be stored in memory. As we put the items the costs will get added to total. Thus the billing will be done at the trolley itself. Item name and its cost will be displayed on LCD. Also the item name and its cost can be announced using headset.
For detecting different items RFID reader will be used. To store the item price and total billing memory used will be Atmel AT24C04. LCD used will be 16X2 alphanumeric display. It will be used to display item names, item cost etc.
At the billing Counter the total bill data will be transferred to PC by wireless RF modules.
