I like the model where you vote electronically and you can see (through a clear material) that the machine prints out a copy of your votes and drops them into a bin.

You can throw cryptographic verification on top of that if you like.

That's one very expensive pen.

Paper doesn't matter if it isn't being counted. Spotting irregularity in voting results might be possible with statistical methods but how often were votes really recounted?

How do you check that your votes were actually taken into account? Even if you can do that, how do you check that no votes were added on top of legit votes?

If the actual votes are printed, how do you make sure no one can prove their vote to third parties and so be paid for it?
