Art ID Tags – Physical NFTs

What is a physical NFT?

Physical NFTs are tags that are affixed to real world objects, which link the object to information stored on a blockchain. Some companies use QR codes, while others, like, use NFC chips.

Different physical NFTs can also use various methods to verify that the physical NFT tag and data on the blockchain are uniquely paired. As examples, one company uses small panes of broken glass, while another uses a chemical analysis of the object.

In contrast,’s patent pending Physical NFT tags take a more crypto-centric approach, storing blockchain related information about the contract, wallet, and token (digital NFT), as well a PGP signed message on the NFC chip, so we can securely and strongly connect a tagged physical object with a digital NFT.

Our Physical NFTs tags come in a variety of styles, including name plates for framed artwork, tags that hang, tags that stick, so they’re easy to place on objects like paintings, artifacts, sculptures, ceramics, art glass, and more.

When you tap the Physical NFT tag with your phone or other NFC enabled device, then it will open the Physical NFT’s menu webpage.Once the Physical NFT’s menu appears, then you can choose to open the associated digital NFT to see the description and provenance, or you can view the authenticity verification, or you can launch a digital experience.

These experiences, related to the object of art or collectible, may include things like VR / Metaverse, AR / Mixed Reality. 360 photos or videos, websites, social media links, and more. The experiences your Physical NFT provides will be clearly detailed in the Digital NFT.

Imagine entering a virtual room with a video where an artist or curator talks about the art. Options like this can enhance the experience of a physical object of art or collectible.

How is Provenance provided?

Provenance is stored in the Digital NFT associated with the Physical NFT tag. The digital NFT can be viewed at the click of a button, from the menu displayed when the Physical NFT is scanned.

A Digital NFT can contain many details about an object of art or collectible. It can include images, video, descriptions and details of the object’s type, origin, history, provenance and more.

In the example to the left, the Digital NFT contains a photo of the object, as well as background information on the artist, a description of the piece, the artist’s name, the dimensions of the piece, the medium & materials used, and provenance listing previous collections, etc. The Digital NFT also associates the object of art or collectible with the current owner through the wallet address.

How is Authenticity Established and Verified?

Authenticity is ascertained by multiple methods.

Firstly, the Physical NFT tag contains data that includes the wallet address, which is like the signature of the artist, collector, museum, gallery, or auction house. The Physical NFT also contains the token id of the Digital NFT which stores the provenance and other details about the object of art or collectible. maintains a registry of wallet addresses (akin to examining the signature or maker’s mark on a physical piece of art or collectible). We check our registry, and we check the blockchain automatically to verify authenticity. This ensures that the wallet address is from an verified source, and that the Digital NFT referenced was sold or transferred from that wallet address and is associated with the Physical NFT tag. This automatically occurs and displays a certificate of authenticity.

Secondly, a unique object ID and an RSA PGP verification key are stored in the Digital NFT’s unlockable content. These can be used to verify the matching signed object ID from the data sent by the Physical NFT tag. This is intended to be done infrequently, usually when the physical object is sold, and the seller transfers the Digital NFT to the wallet of the new owner.

To perform this verification, the new owner uses the Physical NFT to open the menu, and copy pastes from the unlockable content of the Digital NFT. This will then automatically verify that the Physical NFT and Digital NFT correspond, providing an additional certificate of authenticity.





How does a Physical NFT provide Digital Experiences?

When the Physical NFT tag is scanned, the webpage menu is displayed. This can include the display of the Digital NFT in a metaverse or virtual reality environment. It could also open a mixed reality or augmented reality experience that includes a video. 360° photospheres, links to websites, social media pages, interactive videos, and many other options also exist.

Digital Experiences are made more authentic when they are strongly associated with a physical object. Our combination of a Physical NFT and a Digital NFT that are securely tied together, provides unique possibilities.
