The “Smart Billing enabled Shopping Cart” is an Internet of Things invention that will transform the shopping experience. It uses the ESP32 CAM, QR codes, and Arduino IDE. This project intends to improve and streamline the purchasing experience in a future where efficiency and convenience are critical. Traditional shopping carts no longer meet the modern consumer’s needs, which require laborious human data entering. This paper aims to develop a shopping cart that minimises errors, streamlines data entry, and speeds up checkout. Users may scan products with a mobile app using the ESP32 Cam to affix QR codes to each item. It calculates the total cost and produces an itemised receipt. The work shows notable increases in user satisfaction and shopping efficiency. It is a viable option since it speeds up checkout, lowers error rates, and improves the shopping experience. In conclusion, the ESP32 CAM and QR code-powered Smart Shopping Cart provides a creative way to make shopping easier. It solves the drawbacks of conventional shopping carts, which eventually helps consumers. This whole work demonstrates how IoT technology can be used to optimise daily tasks in shopping malls.
