And now days I can't put in my card's pin without 10 overhead cameras aimed at the register area. All the cameras of which are network-connected, video stored persistently, and high res/fidelity enough to here the little beeps as I press the keys, and to know that I've hit the enter because the screen indicates it immediately. But then Dell cared about its own security, and the grocery store doesn't give a single shit about whether my life is ruined by identity theft.
That's why I always cover the pin pad with my other hand (probably also holding my wallet) when putting in a pin. However, I think the more likely scenario to defend against is shoulder surfers - the pin by itself is useless until combined with the card, so physical presence is needed to lift the card from me.
