Abstract - The Internet of Things (IoT) is significantlyimproving the way everyday systems operate, especially in the retail sector. This paper presents the design and implementation of an IoT-based smart shopping trolley that simplifies the billing process and enhances customerconvenience. The system uses RFID technology to automatically identify products placed in the trolley, eliminating the need for manual barcode scanning at checkout counters. As a result, waiting time is reduced and the overall shopping experience becomes faster and more efficient. In addition to billing, the system supports real-time inventory management by transmitting product data to a central server through wireless communication modules. A prototype model is developed to evaluate the performance and reliability of the system. The resultsdemonstrate accurate product detection, smooth communication between components, and effective billing functionality. Overall, the proposed smart trolley provides a practical, cost-effective, and user-friendly solution for modern retail environments. It reduces human effort, minimizes errors, and offers a foundationfor future advancements such as smart s
