Earlier quoted context omitted.
Heads up, If you're an American going to Europe, regular swipe only credit cards won't work as often here. Nearly all point-of-sale credit card machines require chip & pin. Or you'll wind up like some tourists in my local supermarket unable to use their credit card.
This is nonsense (at least in the UK and France). Yes there is preference for chip & pin but every reader I've seen supports swipe & sign still. Chips break, contacts corrode. It's there as a backup. (And yes, this totally defeats the security aspect of C&P)
As I understand it, C&P isn't meant to be more secure for users - it's meant to be more "secure" for banks, since if someone fakes your signature it's not your fault (and the bank has to swallow the loss), but if someone gets hold of your PIN it IS your fault.
