> I have a passport, I have a drivers license. There are individuals who have both of those identifications and a Tribal Nation identity card and a Veteran Health Identification Card too. Four different forms of ID for the same person - can those each be used once? The point of government ID is that you have a complete government registry of allowed people, and ID cards are used to prove your association to that registry. For example, when I go to vote, there is a master list of everyone who is eligible to vote, and my name gets checked off the list. If I tried to vote again, well, my name is already checked off the list and I don't get to vote again because of that. Or put differently, proof of identity isn't the same of proof authorization. ID cards prove identity; some other mechanism needs to prove authority to access the resource, and if necessary, it's that mechanism that prevents repeat access.
