A new law signed Saturday by Illinois Governor Pat Quinn makes the state the 18th in the U.S. to allow voters to register for elections online.
Supporters say the new system will increase voter turnout while cutting the administrative costs of processing registrations on paper.
The governor and supporters are confident the law can be used without the risk of any increase in voter fraud. Election authorities will have until July of next year to have the online system in place.
To register online, applicants will need to use a driver's license and the last four digits of their Social Security number.
