This is required by FEC/NASED standards. All existing precinct-count
optical mark-sense scanners and all existing touch screen voting systems
maintain audit logs that record the time at which each ballot is cast,
minus the ballot cast, and separately, the ballots cast, minus the
timestamp. Comparing the number of ballots counted with the number of
ballots recorded in the audit log is a valuable check on the integrity
of the system. In fact, it is this comparison that led to the
discovery of problems with the ES&S iVotronic system in Miami, problems
that have eaten my time for the past week.
