The machines each print a tally report at the end of the night. The report includes a QR code that encodes the results data.

Gonna go with no, but that would be one sweet deduction.

It's local election day in New Hampshire, and @voting.works is powering elections in 40 towns. Up from 5 towns last year at this time. Exciting to get open-source voting machines to more and more Americans!

We use machines to count in the US because we have 30, 40, 50, sometimes 80 questions per ballot.
