Abstract: Retail inefficiencies caused by traditional billing systems continue to affect customer experience and store productivity. This paper presents a Smart Shopping Trolley system that leverages RFID technology and embedded system intelligence to enable real-time billing within the shopping environment. Unlike conventional barcode-based methods, the system performs automatic product detection and dynamic bill generation directly inside the trolley. The framework integrates an RFID reader with a microcontroller to identify tagged products and update the total bill instantly. A real-time display allows customers to monitor their expenses during shopping, improving transparency and decision-making. This approach reduces checkout time, eliminates long queues, and minimizes human errors. Overall, the system provides a scalable, efficient, and user-centric solution for modern retail automation, enhancing both customer satisfaction and operational efficiency.

Keywords: RFID Technology, Smart Shopping Trolley, Automated Billing System, Embedded Systems, Real-Time Billing, Retail Automation, IoT-Based Shopping, Microcontroller, Customer Experience.
