Access control has matured in recent years. Today’s access control is streamlined and computer controlled allowing management to assign levels of access to each employee. Keypads, magnetic ID cards and key fobs are all used to insure that the person entering a specific space is authorized to be there. Using an access control system eliminates the need to re-key doors and restricted locations when there are personnel changes. It also allows for logging of personnel insuring that you know who entered and when as well as when or if they left.
