It's cryptographically signed by the issuing authority. Nothing can be changed...?
The picture is signed? In any case, using an older sibling's ID still works about as good as ever.
I haven't read the exact spec myself, but I'd be extremely surprised if it wasn't. Unfortunately tech can't solve the problem of doppelgangers without going into biometry, which might be a bit of an overstep for simple ID purposes.
Right, like this whole effort. A bit of an overstep for simple ID purposes, when fundamentally it still depends on somebody looking at the picture and making a call.
