Some additional voting machine feature suggestions… (aka more bad ideas)
Built-in cellular/digital modems for when the wifi goes down so the results can be auto-faxed to the people at the table in the corner 20 ft away.
Microphones so that the can record the mutterings of the voters and send it through a cloud based voice recognition system and applied to machine learning algorithms. Why? Uh, so we can create Word clouds of the election by district. Plus AI is cool man!
Speakers so that it can interact with your phone in higher frequencies than human hearing. That way it can harvest cool voter info.
