The Electronic Cargo Tracking System uses Intelligent Locker Tracker and on-board terminals with GPS, BeiDou, and mobile networks to keep cargo visible and under control throughout transit. Operators can monitor lock status, replay routes, manage remote access, and track shipments in real time through a central dashboard. The system streamlines supervision, reduces delays, and accelerates cargo flow—helping logistics providers improve efficiency, service quality, and competitiveness. It is well suited for freight, express delivery, and cold-chain logistics.
