Fingerprint Scanner That Works From 6 Feet

Bruce Schneier found a somewhat older story that I haven't seen before about a device that is smaller than a tissue box, but uses two 1.3 megapixel cameras and a polarized light source to scan a fingerprint from two meters away.

      2. batch processing. i guess you could ramp it up so it could scan many hands at once so you wouldn't need to have bottle neck barriers more and open walk way (say 20m long) with a couple of guards to double check people who didn't register

      Exactly. Like all security systems, it's not perfect. Using several together can mitigate the flaws in any one system. Biometrics are useful in that they don't require you to carry around anything -- hence they are user-friendly -- and are somewhat more difficult to fake than a traditional key (not necessarily harder to obtain, but at attended posts the guard could notice your fake thumb/eye/weight belt, whereas he could not be expected to notice a fake key).
