The latest in biometric security scanners

Fujitsu has released a small 'camera' that scans the vein structure in the palm of your hand. It snaps 20 images in a second and uses the best one for comparison and authentication. Probably more difficult to spoof than fingerprint scanners (as demonstrated on Myth Busters), but is it hack-proof? I doubt it. Build a better mouse trap and you get a smarter mouse.
