Some of that may depend on precision - how precise is the sensor? Can it pull a fingerprint, so it will basically do a fingerprint scan to authorize door unlock

Some of that may depend on precision - how precise is the sensor? Can it pull a fingerprint, so it will basically do a fingerprint scan to authorize door unlocking? I'm reminded of #66 on the Evil Overlord list - My security keypad will actually be a fingerprint scanner. Anyone who watches someone press a sequence of buttons or dusts the pad for fingerprints then subsequently tries to enter by repeating that sequence will trigger the alarm system. http://www.eviloverlord.com/lists/overlord.html http://www.eviloverlord.com/lists/overlord.html
