Smart Shopping Trolley: A New Revolution

Urban areas, shopping malls experience significant crowds during holidays and weekends, especially when there are substantial offers and discounts available. Currently, shoppers tend to select a variety of items and place them in their shopping carts. After completing their selections, they proceed to the checkout counter for billing. The cashier utilizes a barcode reader to prepare the bill, which can be a time-consuming process, often leading to long lines at the payment counters. This initiative proposes a solution to address this challenge. The plan involves equipping all merchandise within the mall with RFID tags, while each shopping cart will be fitted with an RFID reader and a digital display screen. As items are placed in the cart, their codes will be automatically recognized, and the name and price of each item will be displayed on the screen, consequently adding the cost to the total bill. Additionally, if a shopper wishes to remove an item from the cart, they will have the option to do so seamlessly.The measurement of the specific item is subtracted from the total amount, and equivalent data is transmitted to the central billing unit via the ZigBee module. Consequently, billing can be performed directly from the trolley, which significantly saves time for the customers.
