[@Bazmund] Didn't think about the common name thing. The fakes can hold up, especially if it's from a state with fake ID problem. I.e. Illinois has had a problem for decades. Authorities can't tell just by looking at it. If they decide to investigate it that's when it becomes a problem. So no getting pulled over.

Kai's fake IDs and passports, yes, kinda. Those match personas she's created, so they don't look like her to a T. Half of them the gender is different. If he can use magic to change his look enough, then he can probably get away with it.  Her credit cards and social security numbers, no. He can use any of those as long as the place doesn't ask for ID. Most places don't. And no one needs SS outside of hospitals. 

Also, his magic. Can't he make them see what he wants temporarily? Like the ID looks like him if they're distracted enough for it to work?
