Poll workers have been training for the past several days on how to operate some new equipment that will be used for the first time in Tuesday's elections.
The Electronic Voter Check In, also known as electronic poll books, will be at all polling places in Jefferson City.
For Tuesday's elections, Register said, a voter should use his or her driver's license if they have one. However, a voter ID card is still acceptable to vote with.
Voters may need to allow extra time for voting since this is the first time these devices will be used.
Last November, the Cole County Commission approved purchasing the new voting devices in hopes it would reduce the future cost of elections.
For a cost of $66,715, the county bought 50 electronic poll books.
These books will replace paper poll books to check voter information to make sure the voter is at the right polling place or is properly registered to vote.
