smart line following shopping cart with billing system using RFID

Abstract

Traditional checkout systems in supermarkets can cause long lines and delays for customers. To solve this problem, we've created a smart solution called the Smart Shopping Cart, which uses IoT technology to make the shopping experience more efficient.. This system eliminates the need for standing in queues by allowing customers to scan products with an RFID system and place them in a smart cart. The cart, equipped with a Node MCU and an LCD screen, displays the total price of the items as they are added customers can also see their total bill on a web server, which helps them keep track of their purchases more easily. To improve the shopping experience even more, the smart cart is designed as a robot that can follow a set path in the store.
