Still not good enough. The bits can be manipulated for the printout, and transmitted as corrupted to the central computing facility. Only during a recount would it be caught, maybe. In fact, the scanned version can be manipulated as well, so to match the corrupted version transmitted earlier. The only way, IMHO, is paper and ink dye.
Yeh, I think thats a little far fetched since these machines will not be hooked to the internet. They should work fine.
carbon copy paper ballots...
original for official tallying...
carbon copy for voters for future reference...
ink dye on middle finger...
