The access badge contains a number that is read by a card reader. This number is usually called the facility code and is programmed by the administrator. The number is sent to an access control system, a computer system that makes access control decisions based on information about the credential. If the credential is included in an access ...
In computer security, general access control includes identification, authorization, authentication, access approval, and audit.A more narrow definition of access control would cover only access approval, whereby the system makes a decision to grant or reject an access request from an already authenticated subject, based on what the subject is authorized to access.

The EAPOL was also modified for use with IEEE 802.1AE ("MACsec") and IEEE 802.1AR (Secure Device Identity, DevID) in 802.1X-2010 [7] [8] to support service identification and optional point to point encryption over the internal LAN segment. 802.1X is part of the logical link control (LLC) sublayer of the 802 reference model.

Many access control system manufacturers adopted Wiegand technology, but were unhappy with the limitations of only 8 bits for site codes (0-255) and 16 bits for card numbers (0-65535), so they designed their own formats with varying complexity of field numbers and lengths and parity checking.
