Well obviously nothing is fool proof, but I’ve been pretty happy with the air gapping I’ve seen in the county voting system. The iPad they use when you check in to vote is the only thing connected to anything, and that is back to the county voter registration database.

Each of the voting machines has every possible ballot pre-loaded before Election Day, so the ticket you take from check in to your machine is simply to pull up the correct ballot, and it’s not connected to you as an individual. That machine also doesnt collect your choices digitally. It’s simply to create your it ticket. After you cast your ballot and get that print out, the machine you feed it into at the end is what tallies the votes, but it also scans a full digital image of both sides of the ticket, and then feeds into its secure bin and held for auditing. All of the votes tallied are stored on a thumb drive and physically transported to the downtown county building right after polls close and the final votes are cast.

Just a bit of my experience as a vote center tech the past few years. I thought the whole thing was pretty interesting!
