Authentication

Every Galerie Radial piece is appraised, then fitted with a sealed NFC chip that links it to its digital passport.

Appraised

Period, attribution and restorations are researched and documented by the gallery. Attributions are given with care: what we know, what we believe, and what remains to be established.

Sealed NFC chip

An invisible NXP NTAG 424 DNA chip is built into the structure of the piece. It cannot be removed without being destroyed.

Tamper-proof passport

At every scan, the chip generates a unique encrypted signature that cannot be copied or cloned. The piece's digital passport — description, provenance, history — remains verifiable for life and passes to each new owner.

How to verify

Hold a recent smartphone near the chip location shown on the piece's page. No app is needed: the passport opens instantly and confirms the piece's authenticity.
