I've started to pull and wiggle the card slot a bit before sticking the card in. From these photo's, I have the impression these skimming devices should be a little 'looser' than the regular thing. However, it may be completely useless.<p>My second countermeasure is screening the number pad with my hand while entering my PIN. They can probably make out the PIN from hand movements, but I'm hoping it'll be too much trouble for them and they will just move on to the next, easier, target.
