Cargo does not disappear at the loading dock. It disappears somewhere between the dock and the destination, and by the time anyone notices, the trailer is empty and the seal is lying on the floor. The 4G + GPS/BeiDou (GNSS) Logistics Smart Padlock was built for exactly that gap: it keeps a truck door online, reports every open and close, and lets dispatch authorise access from a desk hundreds of kilometres away.
Traditional bolt seals and plastic seals do one job: they show whether a door was opened. They cannot say when, where or by whom, and once they are cut they are thrown away. A fleet running hundreds of trips a month pays for those seals on every load and still has no usable record when a claim is filed. A reusable electronic seal changes the economics and the evidence at the same time.
The padlock uses an LTE Cat.1 module to stay connected to the cellular network, and multi-constellation GNSS (GPS and BeiDou) to fix its position. The platform shows each unit on a map together with door status, battery level, signal strength and the time of the last update. Positioning does not depend on the driver having a phone nearby, or on a Bluetooth link that breaks the moment the truck pulls away.
Remote unlock is the feature that changes daily operations. When a driver reaches a stop, dispatch can open the lock from the web platform or the mobile app and watch the door status change in the same view. Drivers who do not need to wait for authorisation can use the fingerprint sensor, and an SMS unlock path covers the case of a driver with no data connection. Every event is written to the log with a timestamp and a location.
The system also watches for the events that matter most: an open event outside an agreed window, a cut or tamper attempt, and departure from a geofence. Alerts are pushed to the platform and the app, so a dispatcher learns about an unauthorised opening within minutes instead of discovering it after delivery.
The hardware is built as a reusable e-seal, with an IP67-68 rated housing, a rechargeable battery rated for more than a thousand unlock cycles, and a hardened shackle that resists cutting and prying. It fits trailer doors, container doors and high-value route trucks, and it is designed to be recharged between trips rather than replaced after each one.
The practical value usually shows up in disputes. Instead of arguing about a seal number written on a delivery note, the operator exports a record showing when the lock was closed, when and where it was opened, and whether anything abnormal happened in between. That record exists for every trip, not only for the trips that went wrong.
The mobile app covers drivers and the web platform covers the control room: device list, map view, alerts, reports and settings. For larger fleets and platform vendors, integration with an existing transport management or tracking system can be scoped as part of an OEM/ODM project.
The padlock is available for OEM/ODM and wholesale orders, with options on branding, firmware behaviour, packaging and accessory sets, and volume pricing quoted by tier. Samples are available for evaluation before an order is placed.
Fleet operators, logistics companies and distributors who want to test a unit can request a sample through the contact page, or review the technical specification on the 4G + GPS/BeiDou (GNSS) Logistics Smart Padlock product page.
