Abstract: An access control system for medical and dental computer systems includes at least one computer workstation communicating with a wireless channel that executes at least one wireless protocol that allows communication with and identification of at least one wireless-enabled token through the wireless channel and that controls a predetermined level of system access to the computer workstation for an authorized individual in possession of the token. A wireless-enabled token uniquely identifies an authorized individual wherein the computer workstation is unlocked when the wireless-enabled token resides within the proximity zone and the computer workstation is locked when the wireless-enabled token resides outside the proximity zone.
