Oh no! Imagine you find a willing adult who does the verification on your phone. The whole system is moot!
Don't need "copy" here for that. They can just do the verification on your device without any technical tricks
Yeah. that's where this system fails. It only stores a single attribute that you wouldn't mind putting on someone else's phone. In the full EU wallet the 'over 18' attribute is part of a larger set of credentials that is basically your entire digital ID. If you were to put that on someone else's phone they would be able to identify as you to numerous government and adjacent services. You'd be a fool to share that.
This whole scheme feels a bit rushed and not thought through.
