Voting Systems & Equipment

As of June 13, 2019, this page was still under construction. In the next few days, we hope to have all our past reports, press releases, and other documentation grouped together on this page by voting system. We hope this will allow our readers to locate more easily information about particular types or brands of equipment in use, or being proposed for use, in their locality.

We want to caution the reader, however, that voting systems vary greatly from state to state, depending on certification requirements, updates to equipment, and other factors. For example, Florida does its own testing and certification of voting equipment; Federal qualification is not a prerequisite for certification in Florida.

ES&S iVotronic

In the 2006 general election, problems with the state’s most widely used touchscreen voting machine–the ES&S iVotronic–ultimately led in-coming Governor Charlie Crist to make it his first priority to mandate the use of optically scanned paper ballots throughout the state.

ES&S Digital Scanner 200 (DS200)

In 2007, FFEC research director, Mary (Kitty) Garber predicted that without modifications, a poorly designed overvote feature on the new scanner would likely result in many more lost votes due to overvoting–a common voter error that the feature is designed to prevent.¬† The feature was not modified, and in 2008, Garber’s fears were realized. In Miami-Dade, Florida’s most populous county, Garber found the feature had disproportionately affected minority voters. Garber’s research was later used by the Brennan Center for Law and Justice, as well as election integrity activists in Wisconsin, to push for changes to the feature before certification in other states.
