Alex Knapp is not at all impressed with the spread of touchscreen voting and thinks it will ultimately create more problems than it solves; I generally agree, especially given the less expensive and superior alternative: optical mark recognition (OMR) machines, which are essentially glorified Scantron machines that read ink circles instead of pencil marks. Put an OMR scanner or two in each precinct, and the only other equipment you need are some pens and the proper machine-readable paper ballots. Not to mention that the audit trail is trivial: all you need to do is hang on to the ballots after they’re scanned.
