I just saw this referenced on Reddit:

He found this one on an ATM in front of Hardy's Sanur. It's a camera inside the number pad cover that records you entering your PIN number.
I don't know how they got the card number but the take away message is that you should poke, pry and pull at the ATM to see if anything comes loose before you use it.
