Thermal imaging technology has advanced to the point where it's small and cheap enough to snap on to a smartphone. The heat left behind from you fingers on a plastic or rubber keypad is enough for them to get it 80% of the time. So, like the guy in the video says, rest your fingers for a few seconds on ALL the keys..
Or just do like Gas Bandit, and pay with an actual credit card, which doesn't use a PIN.
