Satellite padlocks have become a key tool for protecting cargo in transit. At NuMar Technologies we explain what they are, how they work, how they relate to customs control in Colombia, and why they’re a smart investment for carriers and logistics companies in Colombia and Latin America.
What is a satellite padlock?
A satellite padlock is a smart locking device that integrates GPS tracking with satellite or cellular connectivity. Unlike a traditional padlock or a simple security seal, it lets you open, close and monitor cargo remotely, in addition to reporting its location in real time throughout the trip.
How do they work?
The padlock is installed on containers, trailers or vans and linked to a management platform. From there you can:
- See the real-time location via GPS.
- Receive unauthorized-opening alerts, with the date, time and exact location of the event.
- Define geofences and allowed routes, with an alert if the vehicle strays off course.
- Authorize opening only at specific points and times.
Satellite connectivity ensures coverage even in rural areas or corridors without cellular signal, essential for long-distance freight transport and border crossings.
Satellite padlocks and customs transit (DIAN)
In customs transit operations in Colombia, cargo moved under the control of the DIAN (National Tax and Customs Directorate) requires security devices — a seal, padlock or electronic device — that guarantee control of the goods throughout the trip. A satellite padlock fulfills that purpose and adds an extra layer of traceability: it reports any unauthorized opening in real time, with verifiable evidence of date, time and location, useful for the customs authority as well as the logistics operator and the end client. If your operation moves cargo under customs transit, we can help you evaluate which padlock fits your route’s and operator’s requirements — contact us to review your case.

Frequently asked questions
Do they need cellular signal? Models with satellite connectivity also work outside cellular coverage, key for rural or border corridors.
Can they integrate with my fleet? Yes, they integrate with tracking platforms like the ones NuMar distributes, including asset trackers.
Do they replace the traditional security seal? They complement it and in many cases replace it, adding real-time verification instead of only a visual check upon arrival at destination.
What happens if the padlock is opened without authorization? The platform generates an immediate alert, with the exact location and time of the event.
Are they suitable for customs transit operations? Yes — they’re a verifiable security device for cargo under DIAN control; we advise you on the right model for your route.
How long does the battery last? It depends on the model and the configured reporting frequency; the equipment we distribute is designed for long trips without needing a recharge.
