That's fine, but your previous statement is exceedingly imprecise
in an important way. There are reliable punch-card voting
systems--those that use a card punch to cuts rectangular holes
in the cards, rather than a pin to push out a prescored circular
chad. IBM card punches were engineered to have less than one
incorrect punch in a billion.

True punch-card systems would not have the hanging chad problem,
but they cannot easily be verified by the voter.

Yes, optical scan has long been known to be the best
voter-verifiable hard-copy technology.

Unlikely, but irrelevant. The public can't tell the difference
between card punches and push-out pins.
