> You can't do this. Probably the most fundamental problem with electronic vote verification is that you cannot give someone physical evidence of how their vote was cast, because it makes voter coercion feasible. There are machines that print paper receipts to voters (presented under glass so voters can verify), and then drop the receipts into a traditional lockable ballot box. The voter cannot access the paper ballot without evidently tampering with the machine; the only issue is that you'd need a way to get poll workers the ballot at issue without identifying the voter.
