(a) Where applicable, every ballot utilized during the course of any electronic voting system election conducted under the provisions of this article is to have two lines for the signatures of the poll clerks. Both of the signature lines are to be printed on a portion of the ballot where votes are not recorded by perforation or marking, but which portion is an actual part of the ballot deposited in the ballot box after the voter has perforated or marked his or her ballot and after the ballot stub has been removed. Each of the two poll clerks shall sign his or her name on one of the designated lines provided on each ballot before any ballot is distributed to a voter.
(b) After a voter has signed the pollbook, as required in section nineteen of this article, the two poll clerks shall deliver a ballot to the voter, which ballot has been signed by each of the two poll clerks as provided in this section: Provided, That where an electronic voting system that utilizes screens upon which votes may be recorded by means of a stylus or by means of touch, an election commissioner shall accompany the voter to the voting device and shall activate the device for voting.
(c) Any ballot which does not contain the proper signatures shall be challenged. If an accurate accounting is made for all ballots in the precinct in which the ballot was voted and no other challenge exists against the voter, the ballot shall be counted at the canvas.
