Authenticity Guaranteed

We proudly stand behind the genuineness and authenticity of all the products we sell and offer an unconditional money-back guarantee that all products are genuine and original from the manufacturer. Each product carries an unclonable authenticity card that serves as authenticity verification, proof of ownership, and warranty certificate.

What do we do?

We track, trace, and authenticate articles that pass from the source point through a plurality of intermediate points along a supply chain to ensure that each article is genuine. Each item carries a physical identifier in the form of a non-cloneable 3D tag along with a digital identity, or twin, in the form of a blockchain-based token. Verification is as simple as scanning the 3D label via a mobile device.

How does it work?

Our system compares the item with its digital twin on the blockchain. If no match is found, the item doesn't pass as authentic. If a match is found, other details (e.g., date, time, location) are added to the blockchain for traceability purposes. Our solution combines the power of blockchain digital security with unique product identification to securely and reliably track product history.

How secure is it?

Each item is provided a unique physical identity at the source by attaching a 3D randomly distributed particles-based tag. Depending upon the size of the tag and the particle sizes, the possible combinations of unique three-dimensional particle distributions are almost limitless. Therefore no two image patterns are ever going to be the same. It is impossible for any company, including us, to be able to recreate an identical tag. Alternatively, we use physically unclonable functions (PUF) that exploit the physical factors of the product itself that are unpredictable and can be used for authentication.

Blockchain tokens act as a virtual certificate of authenticity that is much harder to steal, forge or hack than a piece of paper, barcode, or digital file. Unscrupulous parties cannot compromise our supply chain, and we assure that consumers are indeed receiving authorized or genuine articles.
