None of this precludes hand counting. In fact, I'd strongly recommend random spot checks where hand counts are compared against machine tallys.
One thing I didn't mention, which I'm probably going to be adding to the document is the initial validation steps. As designed, it would be trivial to boot up the computer, and have the initial values validated against a printed or electronic document that would demonstrate that the card was virgin, and in it's initial state. It would, as a part of its boot process display those values, and any observer would be able to see what the initial state of the machine was. A similar screen would be displayed, stored and possibly printed when the voting is over. This would be the initial indication of the machine state.
No, the original tallies need to be hand counted—with plenty of local businesses.
The tech you propose is still an invitation to fraud. I’d go so far as to call it an attractive nuisance for political critters.
