System Overview

VotingWorks consists of two subsystems:

  1. Central System: all the equipment necessary for use at election central for on-demand ballot printing, election programming, central batch ballot scanning, and results tabulation.

  2. Precinct System: all equipment necessary for use at the precinct to scan hand-marked ballots and provide an accessible ballot marking device for voters unable to hand mark paper ballots.

Central System

VotingWorks Central System includes two products:

  1. VxAdmin: the main tool for local election administrators, which programs elections, prints ballots, and tabulates results on election night.

  2. VxCentralScan: a central scanner used for rapidly scanning absentee ballots on election night.

Precinct System

VotingWorks Precinct System consists of two portable, self-contained products:

  1. VxMark: an accessible ballot marking device and attached printer that produces a voter-verifiable paper ballot.

  2. VxScan: a voter-facing precinct scanner that scans paper ballots and notifies voters of ballot issues for second-chance voting.

Voters at the precinct vote on hand-marked paper ballots with the ability to vote on a VxMark if requested. After marking ballots, all voters scan their ballots using VxScan.

Paper Ballots

All votes cast using VotingWorks are on paper ballots for security and post-election auditing.

There are two types of VotingWorks paper ballots:

  • Hand-marked paper ballot

    • All absentee voters will receive a hand-marked paper ballot that is printed on-demand. Absentee ballots are scanned by election administrators using a high-speed central scanner (VxCentralScan).

    • Most in-precinct voters will receive a hand-marked paper ballot that is printed in-bulk or on-demand. Precinct ballots are scanned by voters using a precinct scanner (VxScan).

  • Machine-marked paper ballot (via ballot marking device)

    • In-precinct voters may request to use the accessible ballot marking device (VxMark), which prints a voter verifiable paper ballot. Machine-marked precinct ballots are scanned by voters using the same precinct scanner (VxScan).
