> If technology does not include some additional biometric property (blood vessel arrangement, unique capacitance?!, unique heat signature that will not change over time?! ...) The fingerprint technology which is used appears to be from http://fingerprints.com/ http://fingerprints.com/ . It means the tech is based on an "image" from capacitance, not optics. It also has what is called "liveness" detection - it will be able to differentiate between a dead object and a finger which is alive. So it would not even be enough to cut the finger off.
