Access control systems are physical or electronic systems which are designed to control who has access to the premises. The most simple example of a physical access control system is a door which can be locked, limiting people to one side of the door or the other.
In some cases, physical access control systems are integrated with electronic ones. For example, a door may be unlocked with a swipe card, a key fob, or through biometric means.
