Smart e-seal padlock combining 4G connectivity, GNSS positioning and fingerprint unlocking. Track container / truck door status in real time, receive open & geo alerts on the platform, and authorize drivers remotely — the modern replacement for disposable seals.

Where the 4G Smart Padlock Deploys

• Container and trailer doors — replace disposable bolt seals on international and domestic lanes with a reusable seal that reports its own position
• Rail wagons and intermodal units — the door hasp fits the lock body, and buffered logging covers long stretches without cellular coverage
• Warehouse and yard gates — enroll yard drivers once, and every gate opening is attributed to a credential and logged
• Customs-supervised and high-value lanes — event-level evidence supports inspections, audits and insurance claims

Reusable E-Seal vs Disposable Bolt Seal

	Disposable bolt seal	4G smart e-seal
Proves the load was sealed at origin	Yes	Yes
Proves when, where and by whom it was opened	No	Yes — every event logged
Reusable across trips	No	Yes — rated for 1,000+ lock cycles
Remote driver authorization	No	Fingerprint, one-time code or platform command
Alerts	Physical evidence only	Real-time open, cut and geofence alerts
Cost model	Cheap per trip, recurring forever	Higher upfront, amortized over years of use

Deploying the Padlock Across a Fleet

• Set the reporting interval to match the lane. Frequent reports while moving, sparse reports while parked — the interval trades battery life for detail and is adjustable from the platform.
• Draw geofences around yards and handover points. Exit alerts fire the moment a trailer leaves the corridor it should be in.
• Enroll drivers remotely. Credentials are issued and revoked from the control room; a driver who leaves the fleet loses access without a site visit.
• Plan the charging routine. USB-C charging keeps locks in service, and the battery and SIM are field-replaceable in minutes.

Frequently Asked Questions

How does the 4G smart padlock compare to a disposable bolt seal for fleet insurance?

A plastic seal proves the load was sealed at origin. A 4G smart padlock proves when, where and by whom the load was opened — every event is timestamped, geotagged and tied to a credential. Most underwriters accept the digital evidence as superior to physical tamper-evident seals.

What is the typical position accuracy during transit?

In open sky, the multi-constellation GNSS receiver reports position to within 2 to 5 metres. In urban canyons or near shipping containers, accuracy may degrade to 10 to 20 metres. Geofence entry/exit alerts fire on best-available position, with the underlying accuracy logged for audit.

How is the lock powered and what is the field-replacement procedure?

The padlock is rechargeable via USB-C; a full charge supports 30 to 60 days of normal fleet use. The battery and SIM are field-replaceable, so a service technician can swap them in under five minutes without sending the lock back to base.

Can the padlock operate outside cellular coverage?

Yes. The padlock keeps logging every event locally — open, close, tamper, position where available. When the lock re-enters coverage, the buffered events upload in order. Geofence rules are evaluated at the platform, but the lock itself never depends on connectivity to make a credential decision.

How do I authorize a driver to open the lock?

Authorised drivers are enrolled remotely through the cloud platform. They unlock with their fingerprint, a one-time code, or a remote unlock command from the control centre. Each method is logged with the driver identity, time, and GNSS position.

What happens if someone cuts or forces the seal?

A cut or forced-opening event is pushed to the platform immediately — not held for the next scheduled report. The alert carries the last GNSS position and the event timestamp, so response teams know where and when the seal was attacked.

How long does one e-seal last in service?

The lock is rated for more than 1,000 unlock cycles and carries an IP67-68 housing, so rain, dust and sea spray are routine operating conditions. Under normal fleet rotation a single unit serves for years, which is what makes the cost-per-trip argument work.

Can one control room manage locks across multiple regions?

Yes. Locks report to the same web platform regardless of region, and every event — unlock, tamper, geofence crossing — is logged with identity, time and position. Ask about SIM and coverage options for the specific lanes you run.
