Container Seal Verification

Tap the seal

No seal has been scanned yet. Hold your phone against the NFC seal on the container — the verification page opens automatically. No app, no account.

How to verify

  1. 01

    Unlock your phone

    NFC only works while the screen is on and unlocked.

  2. 02

    Hold it against the seal

    Touch the top back of your phone to the seal on the container door. Each tap opens a result page.

  3. 03

    Tap again if asked

    If the first result is not conclusive, the page asks you to tap the seal once more.

  4. 04

    Read the result

    Intact seals show the seal ID, scan count and full history. A compromised seal shows a clear warning.

  • Remove thick cases or metal plates from the back of the phone.
  • Move the phone slowly across the seal to find the antenna.
  • Damaged or missing seal? Report it to the site supervisor immediately.

Location sharing may be requested during verification to log where the seal was checked.
