Is a paper-vote a reference to literally marking a piece of paper, or a human counting said piece of paper? Sorry if that's a dumb question, just want to make sure I follow. It seems like this tech works with marking a piece of paper that is then read by a machine. I suppose if the paper is kept, perhaps it's nice from the point of view of the election-handling-folks to automate the counting process, but be able to audit the paper ballots?
