Reduce in-transit tampering, swaps, and fraudulent hand-offs while minimizing cost and operational friction.
Who gets which tier?
Tier 2 – Passive E-Seal + GPS add-on: high-value goods, pharma/cold-chain, DG/ISO-tank, routes with hijack history, corridors with insecure parking.
Workflow (end-to-end)
1. Apply & register – Seal applied; Seal ID written to manifest/TMS and printed on hand-off docs.
2. In transit –
➤Tier 1(L1): driver/app sends planned-stop pings; no “seal-open” expected before lawful release.
➤Tier 2(L2): GPS feeds route/geofence/dwell; tamper-independent seal tracks open/not-open.
3. Scan at each control point (gate, depot, cross-dock, consignee) – UHF/NFC scan updates timeline; Seal-ID continuity is verified.
4. Decision – Any seal-open before release or Seal-ID mismatch ⇒ Secondary inspection (RED); otherwise fast lane (GREEN).
5. Evidence – One click exports a 30-second evidence pack (signed timeline + CSV/JSON).
Where the savings come from
1. Tiering avoids over-instrumenting every box; GPS is reserved for cargo/routes that truly benefit.
2. Seal-open-only logic removes false positives from vibration and simplifies training.
3. ID-continuity catches swaps/forgeries without opening containers.
Risk-tiered container security. Use a dual-frequency passive RFID E-Seal on every move and add a clip-on GPS tracker only for high-value or high-risk routes. Simple seal-open detection and Seal-ID continuity catch swaps and tampering without opening boxes, while Tier-2 GPS adds geofence and dwell intelligence. One click produces a 30-second evidence pack to keep clean cargo moving and stop losses where they start.
