In the modern world all supermarkets and hypermarkets use shopping baskets and shopping carts to help customers select and store the products they intend to buy. Customers have to drop all the products they want to buy in the shopping cart and then proceed to check in the billing counter. The billing process is quite tedious and time-consuming and has created the need for stores to increasingly employ human resources in the billing section and yet the waiting time is still considerably high. In this paper, it seems opportune to propose the "Smart Cart of Purchases", which aims to reduce, and possibly eliminate, the total waiting time of the customers, reduce the labor requirement and the total expenses of the markets and increase the Efficiency in general. In a world where technology is replacing the ways we pursue everyday business, the future of the retail industry also rests on increasingly automated devices.
Working
An RFID reader with electronic hardware system in equipped with the cart to make the purchase comfortable. All items are equipped with an RFID card whose price is fixed on the card. When the item is displayed in front of the reader (installed on the cart), the item quantity is added to the purchase invoice and displayed on the LCD. It also has the arrangement to remove the cart items where the cost of the total cost is removed. Once the items are added the cost is added and if it crosses a certain limit, say above 500 Rs or 800 Rs, it gives an alarm signal to indicate that.
