Auth3D vs Cerfinity

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.

Cerfinity authenticates products and records their custody through a provenance record linked to tamper-evident seals with unique cryptographic identities. A customer can check an item by tapping an NFC seal or scanning a QR code without downloading an app or creating an account. The seal can record an irreversible change when packaging is opened, and time-stamped entries can document custody at authorized checkpoints such as producers, distributors, logistics partners, and retailers. Authentication options include NFC, covert micro-mark authentication, and QR verification. Brands can access supply-chain views and counterfeit-concentration data. Listed sectors include spirits and wine, luxury fashion, graded collectibles, specialty food, pharmaceuticals, beauty, and electronics. The pharmaceutical offering includes serialization support, cold-chain monitoring integration, track-and-trace, recall management, and pharmacy-system integration. Cerfinity says its records can support EU Digital Product Passport, EUDR, and FSMA Rule 204 traceability needs. A qualifying brand can use a 30-day pilot with 500 certificates and white-glove onboarding. The Founding Partner plan is $249 a month; NFC seals are billed separately by unit.
