NFC cryptographic proof
NTAG 424 DNA scan values are verified by Timeless. Secret keys and SDM cryptography never run in the browser.
Verify certificates and physical records, follow provenance, and use a genuine NFC tap for NTAG 424 DNA cryptographic verification.
Public verification
NFC scans are intentionally not entered manually here. Tap the physical tag so its dynamic cryptographic values are supplied by the NTAG 424 DNA chip.
Trust model
NTAG 424 DNA scan values are verified by Timeless. Secret keys and SDM cryptography never run in the browser.
Public certificate records show their current current status, issuer, claims, and linked cultural asset references.
Product and NFT pages present the provenance events returned by Timeless rather than inventing missing history.
Where an NFC binding includes Protocol V1 asset data, Timeless reports Timeless-checked chain status and trust result.
