Choosing a smart cargo seal starts with a practical question: what access point are you securing?
Shipping containers, trailers, covers, hasps and other cargo closures do not all use the same locking mechanism. A seal that works well on a standard container door may not be suitable for an irregular access point.
VYND addresses these different applications with two connected smart-seal formats: the Bolt Seal and Cable Seal.
Both are designed to connect physical cargo security with digital journey information, but their physical formats suit different applications. Understanding that distinction can help you select the appropriate seal without compromising how the cargo needs to be secured.
A bolt seal uses a rigid locking mechanism and is commonly suited to container-door applications.
The VYND Bolt Seal is a single-use connected seal designed to secure a container while linking that physical security point with the shipment’s digital journey record.
Once secured and activated, the device can provide location information and record supported journey events. Teams can then follow information relating to the shipment through the VYND platform.
The Bolt Seal is therefore particularly relevant when the cargo is moving in a container with a compatible door-locking arrangement.
A Bolt Seal may be the appropriate choice when:
The physical access point should remain the starting point for the decision.
Not every cargo access point can accommodate a rigid bolt.
Trailers, covers, hasps and irregular closures may require a seal that can pass through or around the available locking point. This is where a cable format becomes useful.
The VYND Cable Seal uses an adjustable cable to secure different access points while providing connected journey monitoring.
VYND currently offers cable lengths of 350 mm, 1,000 mm and 2,000 mm, allowing the physical seal to be matched more closely to different closures.
After the cable is threaded through the relevant access point and secured, the device can be activated and linked to the shipment record by scanning its QR code.
A Cable Seal may be more suitable when:
The key advantage is physical flexibility without separating the seal from the connected shipment-monitoring process.
The clearest difference is the physical access point each seal is designed to secure.
The Bolt Seal is intended for compatible container-door applications. The Cable Seal provides a flexible format for access points where a rigid bolt is unsuitable.
Beyond the physical format, both products support the broader VYND approach of connecting the cargo security device to journey intelligence.
Both can support location and movement tracking, security and handling events, route and geofence information, and predicted-arrival changes within the shipment record.
This means the decision does not have to begin with which product has the longest feature list. It begins with the cargo and the closure you need to secure.
The access point is important, but it should not be the only consideration.
Cargo may travel by truck to a terminal, continue by rail, spend days or weeks at sea and return to road transport near its destination.
VYND is designed to keep supported information from road, rail and ocean legs associated with the same shipment record.
Before choosing a seal, consider how the cargo will move and who needs visibility during the journey.
Questions worth asking include:
Choosing between a Bolt Seal and Cable Seal is only one part of creating better cargo visibility.
The value of a connected seal comes from connecting physical events with the wider shipment journey.
The VYND technology platform brings available location, progress, milestones and supported security events into a shipment-specific view.
Consider a seal event in isolation. Knowing that a seal was cut can be useful, but it immediately creates more questions. Where was the cargo? When did the event happen? Was it near the destination? What else happened during the journey?
Connecting the event to its time, location and shipment context provides a stronger basis for investigation and operational decisions.
A smart seal cannot depend on continuous cellular coverage if it is expected to move across international supply chains.
Both VYND seal formats are designed to account for periods without cellular service. Supported events can be stored locally and uploaded when connectivity returns.
This helps preserve continuity in the shipment record even when live communication is temporarily unavailable.

There is no need to make the Bolt-versus-Cable decision more complicated than it is.
Start with the physical access point.
Then consider the wider journey: transport modes, duration, connectivity conditions and the information your team needs while the cargo is moving.
