Asset and container tracking protects what you transport — not just the vehicle carrying it. In this guide we explain how it works, its relationship with DIAN customs control, and which equipment NuMar Technologies distributes to protect your cargo from point to point.
What is asset tracking?
Unlike vehicle tracking, which focuses on the vehicle doing the transporting, asset tracking protects the container, the trailer, or the cargo itself. It combines smart satellite padlocks with dedicated GPS trackers for assets that don’t always travel inside your own vehicle: maritime containers, third-party trailers, or rented equipment.
Relationship with customs transit (DIAN)
Cargo moved under customs transit control by the DIAN requires verifiable security devices — a seal, padlock, or electronic device. A satellite padlock fulfills that function and adds real-time traceability: any unauthorized opening is logged with date, time, and location, generating evidence useful for both the customs authority and the logistics operator.

Who is it ideal for?
Foreign trade companies, logistics operators, customs agencies, and any business moving containers, trailers, or valuable assets between cities, ports, or borders.
Frequently asked questions
Does a satellite padlock replace the traditional seal? It complements it and in many cases replaces it, adding real-time verification.
Does it work without cellular signal? Models with satellite backup keep reporting even in rural or border areas.
Does it work with any type of container? It adapts to standard maritime containers, trailers, and bulk cargo covers.
What’s the difference between a satellite padlock and an asset GPS? The padlock controls opening; the asset GPS locates something with no closing point (machinery, a full trailer) — the two are often combined.
Can I integrate it with my logistics operator? Yes, the platform exposes reports and alerts that can be shared with your operator or end client.
