It uses the government ID, which has a built in NFC chip. You can use a phone in combination with your ID and it’s pin to verify your age online. The ID scanner app will tell you which parameters the website requests from your ID, and its possible to only request the birthdate.
I don’t like the system, but it is truly anonymous

Sounds like it is only anonymous if you fully trust the app. That app has all your information, and the site you are trying to access. And I bet it is completely closed source. It also likely has logs about what sires it is giving information to. Not who’s info in that log. But elsewhere it probably has logs on who’s id it verified. Get access to both, and software can start to crunch the numbers and figure out who went where. That if course is assuming they don’t decide in the future that it is worth just keeping that data together in one spot. There is just no entity that could manage that app which wouldn’t have a motive to use the data and power it has.

No, the app is completely open source and has reproducible builds

Now you are starting to sound like you know what your talking about. But I’m not convinced yet. So when the app sends just the requested data to the site, how does the site verify that the data is legit. A person could fork the app and hack it. I am sure they thought of this, I just don’t know what thier solution is. And I can’t read german.

(NotOP) these things will usually use cryptographic signatures and if the app has been altered, it’d fail the check.
No clue what they are specifically doing though.

I looked deeper are read up. Everything I can find says the age verification function is not anonymous. There is an anonymous login function, but that doesn’t seem to include age verification.
