Thermal keypad snooping

This falls under the "things I wish I didn't know" category (right along with the fact that the guys on Mythbusters built a functional rocket propelled missle in three days using civil war era technology)

This is an article about how to use a thermal camera to determine the combination on a keypad style lock (i.e, on a safe). Pretty scary that this is possible using such a simple technique.

Hmmm... got me thinking on this one. I happen to use ATM cards at some POS terminals like gas stations, shopping malls where the keypad is in wide open view. One strategy I use to protect my pin is to lightly touch couple more keys on the pad in addition to my pin. That way if somebody is snooping they may be misled into getting the pin or the length of the pin.
