DETAILED DESCRIPTION
For purposes of promoting an understanding of the principles of the invention, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is hereby intended, any alterations and further modifications in the illustrated device, and any further applications of the principles of the invention as illustrated therein being contemplated as would normally occur to one skilled in the art to which the invention relates.
Referring to FIG. 1, shown therein is a conventional access control system 100 according to one form of the invention. System 100 includes a central access control 120 and a number of access control devices 140a, 140b. The central access control 120 is associated with an access control database 130 and a credential production system 110 that serves to generate access credentials. In a typical scenario, the central access control 120, the credential production system 110, and the access control database 130 are maintained by security personnel. The security personnel maintain the access control database 130 as a list of all persons authorized to enter various access points 150a and 150b on the premises. The access information associated with each person is gathered from the access control database 130 and is programmed into a blank access credential such as, for example, a smart card or proximity card, using access credential production system 110. Additionally or alternatively, the access production system 110 can be utilized to generate one or more access input codes, with each access input code being assigned to an individual or individuals, to be stored in the access control database 130. This programmed access
4 credential or input code can then be used to access one or more of access points 150a, 150b via presentation to respective access control devices 140a, 140b which can be a card reader and/or a keypad mounted proximate to an access controlled door.
In the system 100, the individual access control devices 140a, 140b are configured to read access credentials. In response to a correct credential being presented to the access control devices 140a, 140b, an actuator (not shown) can be activated which is associated with the respective access points 150a, 150b. To make the determination to activate an actuator and thereby grant access, the access control device 140a, 140b reads the access credential and then transmits the credential or information derived from the credential to the central access control 120 where a look up function is performed. The lookup function can include accessing the access control database 130 to determine whether a credential presented at a given access control device 140 is authorized for accessing the access point 150 associated with the access control device 140. A message indicating the authorization status can be sent from the central access control 120 back to the access control device 140. In instances where the authorization is positive, the access control device 140 can communicate with the actuator of the access point 150 to grant the user access. Alternatively, the message indicating a positive authorization can be sent directly to the actuator of the access point 150 without passing through access control device 140. Other information may be transmitted between the access control device 140 and the central access control 120 to further enhance the integrity of the access control system 100, for example error codes indicating tampering, power failures, etc.
