These ballot boxes are installed on some small percent of polling stations(like 5% or 10% - I don't remember the exact number). But statistical analysis shows that electoral fraud is commited considerably less often on such polling stations. I don't know, whether it is actually more difficult to cheat on such stations(at least there is a physical limitation - you can't put more than one ballot at a time, because it is needed to be scanned, - as opposed to normal ballot box where you can easily put 10-20 ballots at once), or whether they decided to install such automated boxes on polling stations where they had no intention to commit fraud. But my point is: 1) "Paper-voting" is no guarantee of fair elections. 2) Sometimes "hi-tech" may even help you, if you use it properly.
You make a fair point about electronic voting(and I wholeheartedly agree with you), but it looks like you overestimate the reliability of old-fashioned methods.
To summarize, I'm calling you "not-enough-paranoid kook". :)
