I can’t speak for the whole US, but in Connecticut we use a Scantron sort of system where you fill in bubbles on paper and feed it into a machine. This leaves us with a paper ballot in addition to the machine’s totals. Using machines isn’t necessarily a bad thing, it makes the count a lot faster and it’s not like human counters couldn’t lie. If other states don’t have that paper backup though, they should.

We use the same thing for civic and provincial elections in Canada, but for federal it’s strictly hand count only.
