Abstract: A supermarket is a place where customers come to purchase their daily using products and pay for that. Billing in the supermarket takes a lot of time. Billing of products in the supermarket is quite difficult because it takes more time as people have to wait for a long time in a queue for billing. Looking at the advancement in technology, we came up with an innovative idea of “Smart Shopping Cart for Automatic Billing in Supermarket”. This project consists of RFID reader, motion detector sensor, Liquid Crystal Display, push buttons, switches and WIFI module. In this system product in the mart will have RFID tag, and every cart will have RFID reading. The user has to scan the Smartphone with the shopping APP to select the trolley. When a user put some product in trolley then its code will be detected using RFID reader and cost of a product added to the list and sensor will sense the direction of motion of the product for fault detection. In case, if the user wants to remove some product then a user should press the remove switch and product code will be detected by RFID reader. At last, while exiting the supermarket, RFID at the exit will detect the cart and the user have to scan the Smartphone with the APP for billing for paying the bill and open the gate
