Access control systems are made to control passage into, or out of, an area. The 4 parts of an access control system include: credentials, readers, control panel, and door locks.
Credentials include prox card, magnetic strip card, fingerprint, fob, smartphone, or pin.
Readers include card reader, fingerprint scanner, receiver, or keypad.
Readers convert a credential into a unique ID number.
Then there’s a control panel that compares the unique ID to an approved white list of ID’s.
If the ID is approved by the control panel, then the door lock will disengage and allow access into the area.
