EUDI Wallet Digital Product Passport Verifiable Credential

eIDAS 2.0 requires every EU member state to issue a European Digital Identity Wallet by Q4 2026, and both it and AuthiChain call their records “verifiable credentials” — but a wallet credential identifies a person, while a product passport identifies an item, and the two specs share a name without sharing a subject.

Why AuthiChain

• The EUDI Wallet issues personal credentials — national ID, driving licence — in SD-JWT VC and ISO 18013-5 mdoc formats under the eIDAS 2.0 Architecture Reference Framework; AuthiChain issues item-provenance records as W3C VC 2.0 with an Ed25519 Data Integrity proof
• A product passport does not need a holder to carry it in a wallet — it resolves from a GS1 Digital Link URL that any verifier can query directly, with no presentation protocol or holder binding required
• The two are complementary, not competing: a future EUDI Wallet credential could reference an item’s AuthiChain record for a receipt or warranty claim, but neither spec depends on the other existing

How it works

Issue a unique identifier per unit, anchor its record on-chain for tamper-evidence, and let anyone verify it with a single scan. Plans start at $49/mo.

FAQ

Does AuthiChain verification require a consumer to have a EUDI Wallet?

No — verification runs offline against the signed record itself. The EUDI Wallet stores personal identity credentials; nothing about checking a product’s authenticity depends on the buyer having one.

When must the EUDI Wallet be available?

eIDAS 2.0 requires every member state to offer at least one wallet by Q4 2026, with large platforms and regulated sectors required to accept it for authentication by late 2027 — a personal-identity deadline, not a product-passport one.
