The in the course of my work, I have visited various secure government facilities since the mid 80s. Over the years, I've noticed all sorts of biometrics devices installed at the entrances to these facilities - fingerprint/hand geometry readers, face recognition systems, even a "booth" that was supposed to combine all of these with a body weight measurement to boot. I have nver seen one in actual day-to-day operation; in fact, most of them were abandoned. I've often wondered how much taxpayer money has been wasted on these things.
