This is totally gross. I was walking by the Fujitsu booth when I saw the vein-scanning PalmSecure mouse that uses the veins in your hand to log you into a PC. I figured it wouldn’t look that bad — like a fingerprint at worst — so I asked the guy to run the demo for me. He placed his hand over the mouse for a few seconds and then his vein scan popped up…

Worms, Roxanne! Worms!

It looked like worms. Like really squirmy worms inside his hand. Seriously: if someone made me use this system at work, I’d refuse. There is no way I’m greeting my day with a picture of the veins inside my carpal-tunnel-twisted hand.
