This paper presents the RFID-based smart shopping cart, which helps people to avoid standing in queues for checkout at a counter. It is a more advanced technology system than a bar code reader and allows users to scan their desired items themselves with RFID. The item is added to the cart, and the information is shown on the screen after scanning. The cart with Load cells at the base triggers the safety alarm to ensure the scanning of the purchased item. The RFID scanner and the LCD have been controlled through Raspberry Pi, which acts as a controller. The web application updates product information when the Raspberry Pi is connected to the internet. The user can use the delete button to remove a product from the cart. Testing of the smart shopping cart shows that RFID scans the product, and the message is displayed on the screen.
