Smart Shopping Trolley with Automated Billing Using Arduino

The Smart Shopping Trolley with Automated Billing using Arduino is an innovative system designed [1] to enhance the shopping experience by reducing checkout time and efficiency improving. This project integrates RFID technology, load sensors, and Arduino microcontrollers to automate the billing process within the trolley itself. Each product in the store is equipped with an RFID tag, and as customers place items in the trolley, an RFID reader detects and records the product details. A display screen on the trolley shows the total cost in real time, allowing customers [2] to monitor their expenses. Additionally, a load sensor helps verify product placement and prevents fraud. Upon completing the shopping, customers can directly pay through a mobile application or an integrated payment gateway, eliminating the need to wait in long checkout queues. This system enhances convenience, minimizes human errors in billing, and streamlines the retail experience. By integrating IoT [3] and automation, the smart shopping trolley offers a futuristic approach to retail management, reducing operational costs for stores and providing a seamless shopping experience for consumers.
