The Physical End of the Digital Product Passport

Field notes

The page describes a four-part workflow: selecting the carrier’s material and geometry, assigning item-level identifiers, associating the physical object with a digital record, and preserving access across service, repair, resale, or ownership changes. Supported mechanisms include QR, Data Matrix, NFC, serialisation, and secure ICs. Marked Matter also distinguishes identification from authentication and says regulatory compliance depends on the wider system, including data governance and credential architecture.
