It is the external and visible Certificate of Authenticity from TokenizArt.

The security hologram with VOID technology metalized label that covers the NFC device acts as a protector and certifier of the tokenized artwork and collaborates as a deterrent to extraction, tamper-proof. It not only has a unique and difficult-to-replicate hologram but also features VOID technology. These labels are part of security sticker systems designed to prevent external manipulation. Upon peeling off the label, the adhesive reveals a text where the word ‘VOID‘ is repeated several times. This designation originates from its English etymology, meaning ‘null’ or ‘invalid’; hence, peeling it off diminishes its value or at least raises doubts about its authenticity.

Designed and intended for all involved parties, primarily the artist, allowing you to secure your artwork. You can receive feedback from visitors; the Blockchain-linked Certificate of Authenticity is a holographic adhesive seal that has an embedded NFC device, tamper-proof, which, once attached to an artwork, maintains its identity throughout its lifespan.

Using blockchain through a unique ERC-721 non-fungible token linked to metadata embedded in both the NFC device and the digital token, we can link each particular artwork to detailed provenance records.

We facilitate the creation of tamper-proof certificates of authenticity and ownership to reduce fraud and protect legitimate art exchanges.
