I wasn't really defending electronic voting machines. They're notoriously unreliable and as you point out are expensive and need replacement with time. I was thinking something along the lines of voting online. There is significant research to support the idea that more people vote when it requires less time and effort to do so. Not just research, there are many political parties in America and elsewhere that try to improve their chances at the polls by making it more difficult to vote and keeping turnout low. Voting online would improve the situation greatly, but it isn't easy to implement. To wit, the problems are 1. How to authenticate a user 2. How to map each voter to a vote, without keeping a record of whom he voted for 3. How to prevent fraudulent votes I've thought about it but I couldn't come up with a good solutions to these.
