Forgive my ignorance, but what type of ID is normal to present to porn producers?

(I have 2 passports, a driver's license and an OHIP card all with my photo and birthday.)

I would want to see every piece of ID a girl could produce before filming her.

EDIT: I just realized in one of the above posts that she has tattoos. Don't you need to be 18 to get inked in most places?

As in, plausible ID, girl has tattoos, she is 18 as far as I can tell?
