If India can give every eligible voter in the country a photo ID to use when they vote and afford enough purple ink for their elections, I feel sure we can match that degree of security for a far lower expenditure than whatever scam the Federal Government is proposing.
“With the dyed finger, everyone has to stick the same finger in the dye, there are few ways around the fact that you already voted once.”

There was a Mark Steyn column during the primary, and he mentioned he was somewhere abroad (forgot where) and they use ultra-violet finger dye. When you go to vote, you put your hand under a black light.
I like this method, as there are some folks who invoke the right to NOT vote. It allows them to not be singled out for their (albeit poor) decision to abstain from voting without reprisal. Well, unless folks at work or wherever are walking around with black lights (which I could see in certain union halls or school faculty lounges).
