Question 1

Can the system distinguish between a deliberate opening and incidental vibration or flex in the packaging material?

Accepted Answer

The reed switch requires a minimum separation distance between the magnet and sensor to trigger an event, so normal flexing, impact, or vibration during road or air transport does not generate false positives. The detection threshold is factory-calibrated for each container closure type to ensure that only genuine lid openings — not handling shock — are recorded.

Question 2

Is the open/close log stored separately from the temperature data, or can it be tampered with independently?

Accepted Answer

Both streams are written to the same tamper-evident memory on the logger and share a single audit hash, so the open/close events cannot be deleted or modified without invalidating the entire dataset signature. Any attempt to selectively edit the event log is detectable in the compliance report.

Question 3

How is open/close detection useful for shipments where the carrier is expected to open the container at customs inspection?

Accepted Answer

Customs inspection events are recorded as timestamped open/close entries just like any other opening, which means the shipper has documentation confirming exactly when and for how long the container was open at a border point and what temperature it was exposed to during inspection. This record can be attached to the customs clearance file to pre-empt any quality dispute.
