My favorite photograph of a fingerprint is when the Chaos Computer Club reproduced the German Foreign ministers fingerprint from a photo. So much for military grade security.

The core problems with biometrics are that:

1) Not revokable (unlike compromised credentials)

2) Not a secret

3) Usually trivial to reproduce and spoof (even "liveliness" tests)
