The e-poll books will be used to check in voters with greater ease when they are at the polls.
Classes full of Chicago election judges are learning how to use the e-poll book after decades of using a thick paper book to check in voters at polling places.
The Chicago election board is finally computerizing the process.
''It centralizes the information, it should make it easier for the judges to react and most importantly it gives accurate information which will hopefully enhance security on election day,'' said Langdon Neal, Chairman of the Board of Elections.
A voter's information in the new system is immediate so, a judge will know if someone has voted early. In addition, if a voter shows up at the wrong polling place, the computer can immediately give the voter the right polling place. Because of redistricting, many voter precincts have changed.
''The old way we have to get their address go through hassle as well,'' said Tony Davenport, an election judge.
The e-poll book shows a voters name, up to date voting information and his or her signature. Voters match their signature on a quick print out, and the hope is to make the lines quicker because it is new, the election board has chosen to roll it for Tuesday's primary because of an expected low turnout.
However, Board of Election Chairman Langdon is confident the e-book will be successful.
''We have learned from the mistakes from other jurisdictions we have internally tested it countless of times,'' Neal said.
But just in case it doesn't work on Tuesday, election judges can resort to the old fashioned way and use the paper books as a backup.
The election judges ABC 7 Eyewitness news spoke with with say they are not worried about learning this new technology. The election board says the system they are using has been battle tested in the states of Georgia and Maryland, which have much larger voter registration rolls than in Chicago.
