sometimes many users have two check outs or two checkins, it happens during the day when two users pass together from the gate and they using one card only.
Such "tailgating" is going to make things really tough on accuracy. What do you want to report if it appears that has happened? For example, do you want a separate report of unresolvable clock entries?
