Voting systems may be used in elections provided that such systems enable the voter to cast a vote for all offices and on all measures on which he is entitled to vote, and that the automatic tabulating equipment may be set to reject all votes for any office or measure when the number of votes therefor exceeds the number which the voter is entitled to cast, and provided that such systems are approved for use by the State Board of Elections.
So far as applicable, the procedure provided for voting paper ballots shall apply when electronic voting systems are used.
