The gap
Your suppliers have the data.
You carry the market responsibility. The information sits in factories and laboratories that will never build European IT. Closing that distance is the whole job.
What sits underneath
A passport is not a webpage.
The public page is the surface. This is the half that has to survive an audit.

Battery passport
2027 arrives a quarter early.
The obligation attaches when goods reach the market, not when they leave the factory. Sea freight moves the real cut-off forward — and supplier data has to be collected long before that.
The difference
One identity. Two questions.
Why should I believe it?
A key inside the chip signs a fresh, single-use answer on every tap. Copying the data does not copy that.
Authentication. The part a printed code cannot do.
Regional infrastructure
Data stays where it was collected.
Each region runs its own database, keys and domain. The label answers the question.
| Region | Domain | Status |
|---|---|---|
| China | authentag.cn | Operating |
| European Union | Dedicated EU domain | In establishment |
| United States | authentag.us | In deployment |
| Australia | authentag.au | Planned |
Straight answer
We will not claim certification.
No EU certification scheme for passport providers exists yet. Any vendor claiming to be approved today is describing something that has not been created.
What we do claim is written down, capability by capability — including the parts still open.

One product, one supplier, one batch — from supplier data to a live passport.
