What is the VVPAT and what is the VBO?
The Hart Voting System’s voter verifiable paper audit trail (VVPAT) is what we call the “Verifiable Ballot Option” (VBO). This printer is attached to the eSlate electronic voting device, and it enables the voter to review a paper summary of the ballot choices cast on the eSlate unit. The VBO provides voters with the confidence that their ballots have an associated paper trail. The paper record can serve as an additional audit trail. Hart InterCivic’s fully integrated and easy-to-use Verifiable Ballot Option is delivered through a self-contained printer that is secured in the voting booth next to the eSlate.
