This is why I habitually run my fingers across the keypad after entering my PIN. Paranoid thinking? Maybe.

I do something similar but I think it's far more likely that a cheap webcam is positioned where it can view the keypad of those who don't screen it well. I always throw in a few "phantom" keypresses when entering a pin for my cc or bank card.
