Today’s security professionals are tasked with controlling access to a wide range of doors, enclosures, and other access points. This inevitably requires different types of electronic access control hardware. A single facility can include hardwired RFID card readers, electronic lock-and-key solutions, and even smartphone-operated locks. The differences between locking hardware traditionally required each user to carry several key devices. Managing permissions for multiple key technologies, possibly controlled by different software applications, is inefficient, unreliable, and costly. CyberKey Flash enables users to carry a single electronic key capable of accessing CyberLock electronic cylinders, CyberLock Flex RFID readers, and smartphone-compatible FlashLock entry points. An intuitive software interface manages access schedules for each user, providing complete control over every locking device in the system. Bluetooth communications even facilitate updating permissions for CyberKey Flash on-the-go. CyberKey Flash is the first key of its kind that can seamlessly operate locking devices from three different technologies.
