Auth3D vs Naimi Digital Product Passport

Auth3D creates product records that connect physical objects with their identity, maker, design provenance, production notes, and supporting evidence. A record can be reached through a QR code, NFC tag, RFID workflow, serial number, direct URL, or typed Unique Part Identifier, and buyers or service teams can view it in a standard phone browser without installing an app. Records may include an image, manufacturer attribution, and owner-facing support context. Visibility options include public, hidden direct-link, private, and password-protected records. Auth3D says published records are designed to keep resolving at the same URL after account activity stops. Its API supports identifier creation or reservation, record creation with image evidence, production-field updates, and record retrieval. The Free Registry includes 10 permanent part records. Production costs $12.50 a month, billed $125 paid annually; Enterprise costs $29.50 a month, billed $295 paid annually. Auth3D is a product identity and lookup layer, not a certification authority.
