A customer taps NFC or QR, sees if the product is real, checks origin and batch, claims warranty, receives benefits and keeps a digital certificate.

Every tap turns security into relationship: origin proof, club, warranty, points, reorder and a contextual marketplace for the brand.

Understand it in 10 seconds
nexID does not force people to understand NFC, cryptography or blockchain. First it shows the product, origin, seal status and the next safe step.
The brand loads batch, photos, labels, rules and allowed claim policy.
The person taps NFC/QR and sees authenticity, origin, map and seal state.
Email or phone plus fresh tap, purchase proof and risk score unlock ownership.
Warranty, club, points, store, optional NFT and resale require product proof again.
Consumer
I know what I bought, where it came from and what I can do next.
Brand
I receive demand, geography, risk, leads, warranty and repurchase data.
Retailer
I validate purchase, reduce copy/replay and unlock benefits at checkout.
One engine for wine, events, cosmetics, agro, health, documents, governments and enterprise assets.
When can ownership or NFT open?
Only after a fresh physical tap, verified email or phone, purchase proof or retailer token, and a risk score that does not look copied.
Trust layers for physical products
Start with QR/GS1, product passport, batch analytics and simple support workflows.
Add Supplier Ops, Tenant Vault, NFC 424, offline verifier, Polygon ownership, IOTA proof and UHF/IoT evidence only where risk justifies it.
Batch tracking, product data and GS1 Digital Link compliance at low cost.
Try itUnique one-time cryptographic signature per tap: impossible to clone or replay.
Try itYour phone or reader works in warehouses and remote areas. Syncs to server when back online.
Try itPhysical opening evidence: the tag changes state if the package was opened or broken.
Try itThe buyer claims the product as theirs: creates a digital twin, activates a transferable warranty and can resell with a verified certificate.
Try itAnchors selected supply-chain evidence as hashes or Merkle roots when audit policy requires it. Private product and customer data stay off-chain.
Try itPallets, cartons and industrial sensors: operational traceability without complicating consumer UX.
Try itPolygon and IOTA are integrated technologies, not official partnerships unless a signed public agreement exists. We do not send every tap on-chain or store private customer data on-chain.
Offline and low-connectivity operations
nexID allows authorized phones and scanners to work in areas without internet. The app securely saves the scan and issues a provisional pass. Upon regaining signal, the system syncs the data and issues the official authenticity verdict.
Security operator registers the device fingerprint and operator.
Backend issues allowed BIDs, policy and key fingerprints only.
The app or reader queues hashed evidence in no-signal zones.
nexID performs final replay, policy, warranty and proof checks.
