The Privaris PlusID is the perfect key fob for security obsessed tech junkies. It is the first key fob with a fingerprint sensor. Once the device has checked your prints to make sure you are who you say you are, you can wave it at a properly equipped door and it will open for you. Your fingerprint information is securely stored right on the device, so your biometric data is never exposed to outside databases or devices. That reduces the risk of identity theft.
