Caldwell County's Voting System

The voting system includes ExpressVote ballot marking devices and DS200 digital scan precinct tabulators to be available at every Caldwell County polling location, as well as DS450 central high-speed digital scanners and tabulators to be used in Central Count to tabulate ballots received by mail. With the voting system, voters will receive a blank ballot at check-in to insert into the ExpressVote ballot marking device and make their selections.

After reviewing their selections on the screen, voters will print the ballot. Once voters have reviewed the selections printed on the ballot, they will insert the ballot into the DS200 digital scanner for tabulation.

This hybrid system allows for the convenience and accuracy of electronic voting, as well as the security of an auditable paper ballot that can be used for manual recounts.

Ballot Marking Device





The ExpressVote uses touchscreen technology that produces a paper-based ballot tabulation. As a marking device, ExpressVote handles the entire marking process, eliminating marginal marks and the need for interpretation of the voter's mark. Voters will receive an activation card (ballot) with their ballot style printed on the card to begin the process. Voters will insert an ExpressVote ballot card into the marking device, make their selections, verify the selections made, and print the ballot. Voters then review the selections printed on the ballot for accuracy before taking the ballot over the DS200 for tabulation.
