Verify a product

Scan the product QR code, tap an NFC chip, or open your verification link

Point your camera at the QR code on the product or its certificate.

With the QR code

  • 1Tap Scan a QR code and allow camera access
  • 2Frame the QR code printed on the product or on its certificate
  • 3The result appears straight away, with nothing to install

With the mobile app

For a product carrying a chip: enable NFC, bring the back of the phone close to the tag and keep contact for two seconds. Cryptographic verification works without an internet connection; online verification remains the most complete.

With a verification link

If you received a verification link or scanned a QR code, verification will happen automatically on this page.
