A diddle count is the number of consecutive swipes by an individual badge at a certain reader that are allowed before an alarm is triggered. Despite its somewhat funny name, choosing the right diddle count is a crucial element of a proper office security system. Access control systems that use magnetic cards will have readers installed at every entry point, where users and employees swipe their assigned badges for access. The diddle count, then, is both a way to monitor if someone is trying to access an area that they should not be entering and a way to check if a particular reader or badge is working improperly.
When someone swipes their card multiple times at a reader and is denied access, either the person or the reader is wrong. The diddle count triggers an alarm if a certain amount of swipes is surpassed, alerting you to the issue. When you investigate, you can either explain why a user does not have access to that particular amenity or check if the reader is denying access to a person who should be allowed to continue. In both situations, you can remedy the issue within a matter of minutes. Set your diddle count higher than two or three swipes because sometimes the reader does not get a proper reading on the first or second go.
