DID + VC for item authenticity

Luxury Goods: make every item verifiable.

Bind each bag, garment, watch or shoe to a cryptographically signed identity, issue Item & Ownership VCs at production, and let customers, customs, and marketplaces scan a QR/NFC for an open green/red authenticity signal.

Create account & start issuing How it works

Keep model codes, serial plates and care cards; add a VC layer for authenticity, provenance and resale.

Item credential (excerpt)
{
  "type": ["LuxuryProductCredential"],
  "issuer": "did:web:veritrust.vc:brand",
  "credentialSubject": {
    "serialNumber": "BR-2025-000123",
    "model": "Satchel 30",
    "materials": "Leather/Canvas",
    "factoryCode": "IT-ABC",
    "productionDate": "2025-03-01"
  },
  "status": "active"
}
Serials remain; VC adds signature, status, and ownership transfer.

Problems we solve

  • Cloned QRs/NFC chips that just open marketing pages
  • No cryptographic proof of origin or batch
  • Hard to manage theft lists, recalls and grey-market leakage
  • Resale lacks portable provenance customers and marketplaces can trust
Who benefits

Brands & maisons — stop clones and control grey-market leakage.

Customers — scan to see a clear green/red signal.

Customs & marketplaces — open verification without special access.

Resellers — portable provenance and ownership transfer.

How it works for luxury goods

1
Brand DID

Your maison has a public Veritrust DID as a trust anchor. It signs all item credentials.

did:web:veritrust.vc:brand
2
Per-item VC + QR/NFC

At finishing/packaging, issue an Item VC and encode a short signed token in a QR or NFC chip.

3
Open verification & lifecycle

Anyone can scan to see authenticity, theft/recall status and (optionally) current owner.

GET /verify/item/{token}

Embedding options

Hardware
  • QR micro-label (laminated, tamper-evident)
  • NFC tags (adhesive or inlining in leather/cards)
  • Optional secure elements for high-risk lines
Software
  • DID binding per item: did:veritrust:item:{serial}
  • Revocation/status feeds for theft/recall
  • Ownership VC transfer for resale

Short use scenarios

Store checkout

Associate scans item; POS records VC link for warranty and theft protection.

Marketplace listing

Seller posts the VC link; listing shows a green badge and item facts.

Customs inspection

Agent scans and sees brand-signed item data and status, no app required.

Resale transfer

Buyer receives Ownership VC; stolen/blocked items turn red on verify.
