Considered by many to be the best CyberKey ever, the CK-Blue2 brings amazing advantages to any business. This Key is so secure, it can be set to only update from authorised SmartPhones, with PIN verification if needed. When not in use – it can be switched off. When mislaid – it can be beeped to help locate it. The ability to update permissions “on the move” makes it ideal for transport, logistics, service engineers and delivery activities.
