Reliability of pricey new voting machines questioned

February 23, 2020

Nearly 1 in 5 U.S. voters will cast ballots this year on devices that look and feel like the discredited paperless voting machines they once used, yet leave a paper record of the vote. But computer security experts are warning that these so-called ballot-marking devices still pose too much of a risk.

Ballot-marking machines were initially developed not as primary vote-casting tools but as “accessible” alternatives for the disabled. They print out paper records that are scanned by optical readers that tabulate the vote.

They cost at least twice as much as hand-marked paper ballots, which computer scientists prefer because paper can’t be hacked. That’s an important consideration as U.S. intelligence officials warn that malicious meddling in this year’s presidential contest could be worse than in 2016.

The machines have been vigorously promoted by the trio of privately held voting equipment vendors that control 88 percent of the U.S. market and are nearly unregulated at the federal level. They are expected to be used by some 40 million eligible voters more than in the 2018 midterm elections.
