| Scenario | GPS only | E-lock program |
|---|---|---|
| Cross-border custody proof | Location at checkpoints — gaps between handoffs | Continuous seal + tamper audit between customs events |
| Seal tamper detection | Movement after hours — may miss subtle tamper | Sub-lock / tamper event with GPS timestamp |
| Driver workflow | No lock control — manual seal checks | One-tap unlock at approved geofences |
| High-value / strategic theft | Recovery after the fact | Deterrence + route deviation alerts on targeted lanes |
| When GPS-only is enough | Domestic dry van, low theft lane, shipper does not require seal audit | — |
“Customs already seals containers.”
→ Electronic seal proves continuous custody between handoffs — not just point-in-time paperwork.
“Drivers will resist new locks.”
→ Train on one-tap unlock at approved geofences; fewer disputes than manual seal checks.
“Too complex for our lane mix.”
→ Pilot one corridor (e.g. Vancouver–Calgary) before scaling customs partners.
