PUBLIC RECORD VOTING. Everyone knows who voted and how.
The is no "in between". You can't know who voted but not how they voted.
In terms of who is allowed to vote -- every polling place I ever visited had an election judge right there to determine who is and is not allowed to vote. If you think someone shouldn't be voting, you can sit yourself down in one of those polling places and point to them and challenge them then and there.
I believe there are only 2 options.
