Question

An employee scans his badge to open a door, but the door does not open. The employee does not have access to the room as part of the job

Answer 1

Most businesses and organizations use some form of card access control system to control entry into their buildings and other facilities. In the event that any card reader door is opened from outside without the use of a valid access card, the system will cause a "Door-Forced-Open" (DFO) condition to occur.
