That’s what I mean. The protocol should be open, so that the software (at least the one running on my host, the opaque smart card does not telecommunicate and is ROM) can be implemented by anyone. No, I would not accept a version that works on some immutable desktop OS with a nonfree client.

It won’t count, and I can’t isolate myself completely.

What IS going to convince them then? I am NOT using Android or iOS.

The thing is that while the EU standard does not limit hardware platforms, it does not mandate neutrality, so I can expect member states to only implement Android/iOS. In any case, I will not use that.

It needs ‘hardware attestation’, so a closed set of OS. It would be much better without any age verification.

I don’t want it, but if it does exist, it should be open!
