We use paper ballots and prefer those over electronic. However in the future it seems there should be a way to have a paper record that includes identification of the voter that cast the ballot.
No secret ballot. I don’t think so.
We have paper too and it is just fine, cheap, and fast.
There is no way to secure electronic voting. Just look around today. Electronic systems are always being defeated. At least with paper, you can see the culprit and a large scale cheating effort with proper oversight is going to be plainly visible.
