The Company's access control systems consist of a range of identification readers, including card readers, hand scanners; a control panel; a personal computer (PC)-based computer, and electronically activated door-locking devices. When an identification card or other identifying information is entered into the reader, the information is transmitted to the control panel/PC, which then validates the data and determines whether to grant access by electronically deactivating the door-locking device.
