Intelligent card access keys
A newly developed access control technology allows information about users to be stored on key-like EEPROM devices. The keys store encrypted information about the user and his or her authorized access activity. Specially developed key readers scan, decrypt, and process the key data, and make the decision whether entry should be granted or denied. The key readers can function as complete, stand-alone facility management systems, incorporating access control, security monitoring, and remote control. In this configuration, the key readers provide anti-passback protection and other special features without requiring any data lines between readers. The key readers also feature sophisticated algorithmic processing for performing complex operations such as two-man control or cross zoned security annunciation. Key readers can also be interconnected with an MCM-1000 Multiples Monitoring System to form a distributed processing local area network. In such a configuration, changes in key reader status can be uploaded to the MCM-1000, and programming changes and operator commands can be downloaded to the key readers.
