Electronic Poll Book (EPB)
1. Device that partially automates the process of checking in voters, assigning them the correct ballot style, and marking voters who have been issued a ballot. May be used in place of a traditional paper poll book. E-poll books can be stand alone at the precinct with a separate copy of the registration list or can be networked into a central voter registration system. They can check and update voter records in real time.
