It can't, because the government doesn't know shit about technology. Someone who knows tech, is close to the government, and isn't corrupt, would have to propose it and explain what this zorro-proof knowy doohicky is. The government knows ID checks because you get checked at bars.

Never been ID checked at a bar in my life. The whole concept is alien to me.

Horse shit. The government has extremely deep expertise in computer science readily available on their payroll and at their beck and call. They literally have DARPA, for instance.
