Flexibility and security are combined with the CK-Blue2 working together with the update facility that works on both Android and IOS (Apple) smartphones. The CK-Blue2 CyberKey is astounding with its 12,000 lock capacity, each with individual date and time restrictions if needed. The same capacility is available in the CK-Flash CyberKey (shown right). The secure update facility makes them both even better. It provides the facility to enable operation of the Key when needed, and disable it when not required, improving intrinsic security. Updates can be PIN secured. Shared (or Job) Keys are handled easily. If the Key is mislaid, there is even a Beep facility to help find it.
