My Android phone prevents me from recording phone calls at the request of my carrier, even though it's totally legal for me to do so in my jurisdiction.
I'm not loving where this is all going.
Luckily there are alternatives in the form of code displays and NFC chips. However, next year I won't be able to watch porn unless I verify my age using a smartphone, no alternatives are planned. Or rather, I have the "free choice" to choose between a privacy preserving ZKP solution operating in the kingdom of Google or uploading my face to a porn site.
Dark times.
(We're not in Denmark, but I wonder how it is going in our jurisdiction ...)
That's probably the issue the other post aludes to. The identity wallet will only be available via Google Play or the Apple App Store (as far as we know). So without a phone and a Google or Apple account, you're won't be able to provide your age information to e.g. PornHub.
MitID is different from the proposed app-based solution for age verification which is designed to not leave a trail. The age verification app will initially be enrolled using MitID (or perhaps by a physical visit to a citizen service point where you can show physical credentials and answer security questions), but subsequent presentations of age verification proofs to service providers will be done without involving a central party.
All in all it is a good design from a privacy perspective. The major issue with it is that ONLY a smartphone based solution is planned, and that there is a high likelihood that it will depend on Play Integrity attestation. This will force everyone to be customers of Google or Apple if they want access to the full internet. I think it is technically possible to also offer alternative solutions based on secure hardware tokens which would still enable people without smartphones to verify their age in a privacy preserving way, but this is not planned.
