Hart(of the hart intercivic) is marketing a scanner based paper ballot reader. The non-dumb element comes in the software that reads the ballot image files.

I have not yet read his proposal but there would need to be some means of discriminating totals for different ballot styles (i.e. different legislative districts). It's a non-trivial issue so I assume he may have addressed it. In precint voting one could possibly get away with one scanner per style as in most locale's a precint only has a few styles (usually 4 or less during primaries) In early voting there can be hundreds of styles. Bernallillo county had to used 43 opscans for each polloing station, each programmed for multiple styles, to accomodate early voting, and bernalillo county would be podunk comapred to precints in major cities.

It sounds to me to be a lot like the scanners that read punch cards. It also has the simmilar functionality as those that read things like gel plates in molecular biology--but those are not handled in firmware.
