North Carolina law only requires that poll workers ask each voter for their name and address. Once that's confirmed, they can vote.

"I can't ask for anything more than that," said Mecklenburg County Director of Elections Michael Dickerson.

Dickerson said North Carolina law is set up so that no one is discouraged from voting. However, some voters wonder if someone could wrongly use their name and vote.

"I think you should have to prove who you are," said Charlotte voter Annette Moosavi.

Donald Alexander voted Thursday afternoon, and he said requiring voters to show ID wouldn't be too inconvenient.

"Making it a little more difficult for just anybody to use your name or your information," he said.

However, elections officials said posing as someone else would be difficult. You'd have to know the person's name and address, know where they vote and also be sure they haven't voted yet already.

"The fear of getting caught would stop me dead in my tracks. It's a felony," Dickerson said.

In South Carolina, voters must bring either a photo ID or their voter registration card to the polls in order to vote.

"The argument against that is it might be an undue burden on somebody to have to produce an ID," Dickerson said.

He pointed out that not everyone drives a car or has an official ID.

North Carolina does require people to fill out a form with their name, address and social security number when they register to vote. Election officials said that's a significant safeguard against fraud.

"When you register, we know who you are," Dickerson said.
