It is impossible (yet) to hack chip & pin. The problem is that even chip cards have a magstripe that can be skimmed. EMV[1] enabled fallback funtionality by default, which is the biggest issue imho. Basically, if your chip is broken, a terminal goes through fallback mechanism and uses magstripe instead. This way you can clone a card with "broken" chip and copied magstripe. Some banks allow to disable (opt-out) magstripe for chip cards, so unless you are in US, you should do that. I've seen some people intentionally scratched magstripe, but I'm not sure it's a very good idea.

Or, you know, take your fingernail and scratch the shit out of the stripe. Or play with some strong magnets. Or sand paper. Or... you get the point

Sure you could. But I'd like to have a backup options in case I end up in strange place that doesn't accept chip&pin or my chip is really broken while on travel. It could be opt-in, so in case I need magnet, I could call my bank and ask to enable it.
