Abstract: The project in this paper focuses on a smart shopping trolley that utilizes human following technology to track and identify the user within a shopping area. In this case, the user carries a tag in the form of a wristband or a card, and the shopping trolley carries a reader that identifies the user. The reader then tracks the user using RFID technology. However, to ensure smooth tracking and safety, the shopping trolley uses a microcontroller to integrate RFID with short-range sensors, providing continuous distance measurements. In this case, the shopping trolley maintains a safe distance from the user. In addition, the shopping trolley can track items and link them to the user’s identification. In this paper, the shopping trolley tests human-following technology in a simulated shopping area. The results show that the shopping trolley performs perfectly in following the user and providing convenience in shopping. Moreover, the paper discusses the limitations of using RFID technology for localisation and proposes a solution.
