The Intelligent Security Tray Return System (Basic) is an automated solution designed for passenger security checkpoints at border control and transportation hubs. It replaces the manual process of returning trays used during carry-on baggage screening, enabling automated tray recirculation, elevation, and intelligent sorting.By integrating advanced control systems, sensor-based recognition, and smart queuing algorithms, the system significantly reduces the need for manual handling while improving passenger throughput and enhancing the overall automation level of security inspection workflows. With a compact and modular design, it can be flexibly deployed in a wide range of checkpoint environments. As a core component of next-generation smart security infrastructure, it helps operators streamline operations, lower labor costs, and deliver a smoother passenger experience.
