Worth a look. The guy claims an error rate for fingerprint/face recognition/et al that makes the technology more of a pain than it's worth.

"Biometrics suffer from a number of problems. These include high error rates; a typical fingerprint scanner will get it wrong about 1% of the time, and most other technologies are worse. The result is that in many applications the false alarm rate is unacceptable. In mass screening, there will be so many more false alarms than real ones that the `boy who cried wolf' effect will discredit the system in the eyes of the public and of its operators."
