Software standards. Vote recording accuracy

The manufacturer shall be capable of demonstrating provisions for accuracy within the software. The system shall detect an attempt to cast a ballot when no voting selections have been made or when no selection or less than the legally entitled number of selections have been made (undervoting). The system shall be able to accept a completely blank ballot, but only after a warning message has been clearly displayed to the voter and the intention to cast a blank ballot has been acknowledged by the voter. For partially cast ballots, the system shall differentiate between intentional undervotes and failure to register one or more selections as the result of hardware or software malfunction. The system shall be capable of interpreting any and all undervotes existing when the ballot is cast as the correct number of "no votes" in the offices and referenda in which they occur. As part of the vote-tally process, the system shall compare the sum of all vote selections and of "no votes" with the total number of votes which can be legally made on the entire ballot and produce an error message to the polling place official if any discrepancy is detected.
