Cryptographic authentication infrastructure powered by bank-grade NFC hardware and distributed verification networks. Privacy-preserving ownership proofs that scale.
"Verify the Asset, Protect the Identity"
Luxury brands lose billions annually to counterfeit products that damage brand value and customer trust
Four cryptographic features that make counterfeiting impossible
Stops Cloning
Verifies the "freshness" of the NFC signal using rolling codes. Every tap generates a unique, one-time-use cryptographic code.
How it works: If counterfeiters try to "copy-paste" the tag data, the system instantly rejects it as stale. NXP NTAG 424 DNA generates AES-128 encrypted rolling codes that cannot be predicted.
Stops Theft
Global "Stolen Register" for luxury goods. Owners can mark stolen items as "Haunted" - making them instantly unsellable.
How it works: Any tap of a Haunted item shows "STOLEN - Law Enforcement Notified". Spirit Transfer is permanently disabled. Distributed registry ensures <50ms global lookups.
Instant Liquidity
Secure digital handshake between buyer and seller. Transfer ownership using Zero-Knowledge Proofs without revealing identities.
How it works: Seller generates Transfer Link → Buyer taps item → ZK proof confirms ownership → Transfer completes in <2 seconds. Buyer NEVER learns seller's name or purchase price.
Proven Provenance
Private history of the item's life. Cryptographically signed events showing repairs, resales, and verifications.
How it works: Each event (service, transfer, verification) is logged with cryptographic signatures. Identities are hashed for privacy. Merkle tree proves log integrity.
We use the NXP NTAG 424 DNA (TagTamper), the most advanced cryptographic NFC chip available
AES-128 encrypted rolling counter generates unique codes per tap. Cannot be cloned or replayed.
Microscopic detection loop breaks if tag is peeled off. Next scan shows "Authenticity Voided".
Works natively on every iPhone and Android. Customers tap to verify - no downloads, no friction.
Ultra-durable NFC chip survives decades of use. Protection that lasts the product's lifetime.
Technical Specs: NXP NTAG 424 DNA • 416 bytes memory • 1-4cm read range • $1-3 per tag
