    but it can’t be

    Not true. You can absolutely implement a boolean true/false function on an ID card. German IDs already have that. All you need is a compatible reader (future versions will work over NFC afaik).

      How do you trust that it isn’t sending identifiable info to them too? Is the software open source and auditable? Is it legally enforced that every hardware uses the open source software?

      I assume that it would need some kind of asymmetric encryption signature on the boolean too, and make it change all the time like OTP? Otherwise I’d think it could be intercepted and forged, right?

      And how would the reader work? Everyone needs to buy a reader to beep their ID to when they want to watch porn?

        And how do you verify the source of the “yes/no” signal is a valid ID card? How do you know it’s used by the person linked to it?

        Either the yes/no is trivially faked (so you might as well skip the formality), or the user secretly does get ID’d.

          The data live on your eID, which is basically a Yubikey except you can’t save whatever you want on it.

          Original page, since I don’t want to paste the full translation: https://meid.minv.sk/?page=frequent-questions%2F#howItWorks


          Some countries in the EU like Slovakia also allow you to use passkeys that basically act as supplement to using physical ID card, so that you can use something better like Yubikeys or save it to your password manager.

          It’s a smard card, there’s no reason why the “yes” can’t be cryptographically signed with a government-approved certificate.

          That being said, fuck age verification online.
