Abstract

Nowadays we can see you a huge rush in the metro cities on holidays and weekends at shopping malls. When there are huge offers and discounts, this becomes even more so. People now buy a variety of items from a day and put them in the trolley. One should approach counter for billing purposes after total purchase. The cashier prepares the bill by using the barcode reader, which is a time-consuming process. This leads to long billing counters queues. This project presents an idea of developing a system to overcome the above problem in shopping malls. All products in the mall should be equipped with RFID tags to accomplish this and all trolleys should be equipped with an RFID reader and LCD screen. When the customer places any product in the trolley, their code will automatically be detected, the name and cost of the item will be displayed on the LCD, thus adding the cost to the total bill. If we want to remove the product from the trolley, the product can be removed and the quantity of that particular product is deducted from the total quantity and the same information passes through the Wi-Fi module to the central billing unit. The billing can therefore be done in the trolley itself, saving the customers a lot of time.
