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.
