Electronic voting in the United States involves several types of machines: touchscreens for voters to mark choices, scanners to read paper ballots, scanners to verify signatures on envelopes of absentee ballots, adjudication machines to allow corrections to improperly filled in items, and web servers to display tallies to the public. Aside from voting, there are also computer systems to maintain voter registrations and display these electoral rolls to polling place staff.
