Actually, I forgot one part of this process of voting here. I haven't seen it in action but here you go.
"If an individual offering to vote does not have or refuses to show an appropriate form of identification, the individual may be allowed to vote without being challenged if a pollworker is able to vouch for the voter's identity and address. Otherwise, the individual may vote as a challenged voter by executing an affidavit that the challenged individual is a legally qualified elector of the precinct."-North Dakota
