Election Systems and Software (ES&S)

All direct recording electronic (DRE) voting machines used after January 1, 2006, must have an accessible voter-verified paper audit trail, pursuant to California Elections Code Section 19250. All voters voting on an electronic voting machine should review and verify their ballot choices on this printed paper record, prior to finalizing and casting their ballot. Once the ballot is cast, this paper record of the ballot is retained inside the voting machine as part of the election audit trail to verify the accuracy of the votes recorded. In accordance with California law, voters do not get a printed paper record of their vote choices.
