Your Certificate of Authenticity has been upgraded

No little paper card, your certificate of authenticity is now secured. A Digital Passport is a digital twin of your physical product that stores authenticity, provenance, and service data. It turns ownership into a simple, verifiable experience and supports transparency over a product’s life.

The benefits

  • Verify authenticity in seconds. Check that a piece you want to purchase is genuine
  • Register ownership. Link the piece to you to unlock owner-only content and services.
  • Transfer easily. When you pass it on, transfer ownership in a few clicks so the next owner has proof and history preserved.
  • Access care and support. Find care guidance, service options, and warranty information in one place.
  • See materials and journey. View key facts about materials and where your piece was assembled.
