Abstract
In metro cities we can see you a huge rush at shopping malls on holidays and weekends.
This becomes even more when there are huge offers and discounts. Now a day’s people
purchase a variety of items and put them in the trolley. After total purchasing one should
approach counter for billing purpose. By using barcode reader the cashier prepares the bill
which is a time consuming process. This results in long queues at the billing counters. This
project 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 total amount and the same information passes to the central
billing unit via zigbee module. Hence the billing can be done in the trolley itself thereby
saving a lot of time to the customers.
