So some POS hacks off my index finger at a POS and I become SOL PDQ after he empties my bank account from an ATM and I can't even ID my HMO for the RN at the ICU after driving there in my SUV? No, thanks.

Well, some of them call for using both biometrics and smart card together, not to mention they are also exploring retina, face recognition, and voice recognition. Hopefully no one will rip out your eye .)

The latest version of this technology senses the difference between a fake finger (i.e. made of silicon) and a real one. Everyone has a small current that flows through their bodies and a "connected" finger is required to make the circuit read the print. Early versions of these devices used a form of "copy machine" imaging that could easily be defeated through the oils left on the glass after lifting your finger away.
