Ever locked out of your own home?…if yes, then you’ll definitely like the Bio Knob that will help you enter your home by scanning your fingerprints. Yes, Tychi Systems’ BioKnob is a special kind of a knob that works with biometric fingerprint scanning for verification. Around 1000different finger prints can be stored in the knob.
But, you can still land up in problem if you forget charging the battery at right time . The knob gives you a warning when just 50 unlockings are left. Failing to which you might end up spending the night out of your home. I think this is the only drawback that this otherwise cool tool has.
