In metro cities we can see a huge rush at shopping malls on holidays and weekends. This becomes even more when there are huge offers and discounts. Nowadays people purchase a variety of items and put them in the trolley. After total purchasing one should approach the counter for billing purposes. By using a bar code reader the cashier prepares the bill which is a time consuming process .This results in long queues at the billing counters. This paper presents an idea to develop a system in shopping malls to overcome the above problem. To achieve this all products in the mall should be equipped with RFID tags and all trolleys should be equipped with a RFID reader and LCD screen .When one puts any product in the trolley its code will be detected automatically , the item name and cost will be displayed on the LCD, thereby the cost gets added to the total bill. If we wish to remove the product from the trolley, you can take away the product and the amount of that specific product gets deducted from the total amount and the same information can be passed to the central billing unit via WIFI module . Hence the billing can be done in the trolley itself thereby saving a lot of time to the customers.
