TamperVerify

A serialized tamper-evident seal. Its guarantee is the oldest one there is: you cannot open it and put it back.

Each seal carries its own serial and a code that resolves on our public rail, so a seal applied at seizure can be looked up by someone who was not in the room.

• Destructive-open construction — removal is visible and permanent
• Individually serialized; each seal registrable at verifyknot.io
• Printed to order, so serial ranges can be matched to a case or batch
• Passive — no electronics, no battery, nothing to fail

What it does not do

Tamper-evident, not tamper-proof. A seal shows that something was opened. It does not prevent it, and it makes no claim about what happened while it was intact.
