PINs easily pinched with iPhone-attached thermal imaging kit

Jeff Lewis

You know - I have a Seek thermal camera for my Android phone and I actually tried this a while ago and it was a flop. The heat differences for normal keypad use just wasn't big enough to register. In the video the user presses hard for a prolonged time to get the pad key to heat up. I don't think that's normal use.
