Bastrop County’s Voting System

Certification of Voting Systems

Key Facts on Security of Voting Machines

On September 27, 2021, the Bastrop County Commissioner’s Court approved the implementation of a new voting system for Bastrop County from Election Systems & Software (ES&S). The new voting system includes ExpressVote ballot marking devices and DS200 digital scan precinct tabulators to be available at every Bastrop County polling location, as well as DS850 central high-speed digital scanners and tabulators to be used at Central Count to tabulate ballots received by mail. The new voting system will be put into use for the first time in 2022.

With the new 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.

3 step voting

ExpressVote Ballot Marking Device

The ExpressVote uses touch-screen technology that produces a paper-based ballot for tabulation. As a marking device, the 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 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.

DS200 Poll Place Scanner and Tabulator

DS200 scanner

DS850 High-Speed Scanner and Tabulator

The DS850 high-speed central scanner and vote tabulator is the fastest central scanner in the election industry. The system is used at Central Count to tabulate ballots received by mail. The DS850 continuously scans and intelligently sorts ballots with its high-speed digital image processing, saving election staff valuable time when tabulating results.

Public Logic & Accuracy Testing 

Texas Election Code Sec. 129.023

  • The first test must be held publicly more than 48 hours before voting begins, and public notice of the test must be posted at least 48 hours in advance.
  • The county testing board – which includes representatives of political parties and members of the public – must agree on a test deck of ballots for which the results are already verified through a hand count.
  • The ballots included in the test deck must include votes for each candidate and proposition on the ballot, overvotes and undervotes, write-in votes and provisional votes.
  • The testing board votes the ballots on the electronic voting machines, recreating the choices from the original test deck.
  • The voted ballots are then tabulated, and the testing board meets to verify the results from the hand count and machine count are identical.
  • Voting machines can only be deployed in a Texas election after the test shows 100% accuracy.

Chain of Custody and Reconciliation Procedures

  • Poll workers must maintain a detailed chain of custody log of each voting system.
  • Before polls open for Early Voting  poll workers must confirm there are zero votes cast on each machine and print a tape verifying zero votes cast.
  • Once all votes are counted on Election Night, each county must complete and publicly post a Preliminary Election Reconciliation for Unofficial Totals (PDF) that shows: how many ballots were cast, how many people signed in at the polling place, how many mail-in ballots are accepted or pending.
    • Mail ballots arriving from military members overseas may be received up to the 6th day after Election Day, which is the same deadline for voters casting mail-in ballots to correct a defect such as a missing ID number or signature.
  • Within 72 hours of the polls closing on Election Day, each election office must conduct a partial manual count to ensure the votes were tabulated accurately, using votes from 1% of precincts or 3 precincts, whichever is greater.
  • Once the county has completed its official canvass of votes, county election officials must complete and publicly post their final Election Reconciliation for Official Totals (PDF), which includes the number of:
    • Early Voting check-ins and counted ballots
    • Election Day check-ins and counted ballots
    • Voters who cast a ballot by mail, and how many were accepted and rejected
    • Provisional ballots submitted, counted and rejected
    • Mail ballots not returned or surrendered
