How Ownership Tag Works
Securing your valuables on the blockchain is simple. Follow these three straightforward steps to create an immutable, tamper-proof record of ownership.
Submit your product's details through our secure dashboard—including serial number, photos, proof of purchase, and any relevant documentation. Our expert verification team carefully reviews your submission to ensure authenticity and completeness. Once approved, we create a unique blockchain-based NFT certificate that serves as your product's permanent digital identity, establishing the first immutable link in its ownership chain.
After your product is verified and approved, we dispatch a durable, tamper-evident micro QR code tag directly to your address. This physical tag contains a shortened URL that links directly to your product's blockchain certificate. Simply affix it to your item to create the physical connection to your digital identity. For brand partners and manufacturers, we offer seamless integration options to embed these tags during the manufacturing process, making authenticity verification a built-in feature of your products from day one.
Your product is now protected with blockchain-backed verification. Anyone can instantly verify its authenticity by scanning the QR code with any smartphone camera. The scan immediately reveals the complete ownership history, NFT certificate details, blockchain transaction records, and optional Digital Product Passport information. Our advanced AI-powered Tamper Check feature analyzes the physical tag in real-time, detecting any signs of forgery or tampering, providing an additional layer of security that blocks impersonation attempts instantly.
Authenticity Across Industries
From priceless artifacts to life-saving medicines, Ownership Tag provides a universal standard for trust and verification.
Preserving an Artifact's Legacy
An auction house acquired a rare Roman coin, but its provenance was a mix of fragmented paper documents, creating doubt among potential bidders. The house faced the risk of the artifact fetching a far lower price at auction due to this uncertainty, as high-value collectors demand an unbroken and verifiable chain of custody. Their task was to establish an unforgeable, single source of truth for the coin's history to instill absolute confidence and maximize its value.
To solve this, the auction house turned to Ownership Tag. They meticulously cataloged the artifact, uploading high-resolution scans of all historical documents, previous expert appraisals, and detailed photographs of the coin itself. This comprehensive data set was then used to mint a unique digital certificate on the blockchain, with a corresponding QR code created for the physical display case. This action transformed the coin's disparate history into a unified, tamper-proof digital record accessible to anyone in the world.
The result at auction was a resounding success. Bidders, able to scan the code with their smartphones and instantly review the entire, verified history, competed with unprecedented confidence. The coin sold for 30% above its highest estimate. The new owner received the digital certificate via a secure, on-chain transfer, making them the new, undisputed custodian of the artifact's rich legacy. This permanent digital record now protects the coin's value for all future transactions, ensuring its story can never again be lost, disputed, or forged.
