The purpose of this Article is to authorize the use of Direct Recording Electronic Voting Systems approved by the State Board of Elections. In a Direct Recording Electronic Voting System, voters cast votes by means of a ballot display provided with mechanical or electro-optical devices that can be activated by the voters to mark their choices for the candidates of their preference and for or against public questions. Such voting devices shall be capable of instantaneously recording such votes, storing such votes, producing a permanent paper record and tabulating such votes at the precinct or at one or more counting stations. This Article authorizes the use of Direct Recording Electronic Voting Systems for in-precinct counting applications and for early voting in the office of the election authority and in the offices of local officials authorized by the election authority to conduct such early voting. All other early ballots must be counted at the office of the election authority.
