NFC Verification

Tap your RKT Grading slab on your phone's NFC reader to verify its authenticity. Each slab contains a tamper-proof NFC chip that cryptographically proves it is genuine.

How it works

  1. Hold your phone near the NFC chip on the slab
  2. Your phone will open this verification page
  3. The chip generates a unique cryptographic signature
  4. We verify the signature to confirm authenticity
