You might want to think about that a little further. This is an excerpt from a piece I first posted in 2003,
The concerns are on two levels. First, from the perspective of those not familiar with the technology, it is a device whose inner workings and inherent security they cannot possibly understand. If they can't understand it, how can they be assured that it is honest? Second, those who DO understand signal processing, software, and communications technology know that is far too easy to defraud the system in a way that would be irreversible and undetected. Either way, touch-screens are a loser.
Now, as users of ATMs, cell phones, the Internet, and other electronic media, it might at first seem a little strange that so many people have such concerns. Upon further consideration however, the key distinctions between voting and a service handling mere money become obvious:
Governments are monopolies. One can go down the street to another bank and take the offending bank to court. An evil government can land you in prison (or worse) because they ARE the court. The stakes associated with voter fraud are far higher than with an ATM and so is the temptation to defraud the system.
People are allowed (and encouraged) to compare their own records with those of their financial institutions. In a secret-ballot system, such comparison is impossible.
