This is pretty scary stuff, I mean fuck, every time I see a story like that I can't help but be amazed at how incredibly insecure the services of credit card companies are, and how hypocritically they behave at every single step about security.

And that's why we use chips instead of magnetic strips nowadays.

The one with the keylogger-featuring keypad is what has me most worried, someone could rob me of my card a bit later. Then again, they might as well rob my card and demand the code, having someone else try it while keeping me at gunpoint. Yeah guns are outlawed here, but that doesn't mean they don't have 'em.

Crypto is cool, until you mention physical security. Obligatory: http://xkcd.com/538/

I live in a European country where chips are common. Yet, about one year ago I encountered a skimming device (I ripped it off and brought it to the cops). Unless magnetic strips are completely disabled (domestically and abroad) the security issue is still there.

Incidentally, one of my banks by default blocks all use of Maestro (the European debit card system) outside of the Eurozone. You have to activate use of Maestro abroad on a trip by trip basis. One of my other banks automatically blocks credit cards used in the United States unless preceded by cash withdrawal at an ATM.

I've yet to see a card where all the required information to clone the card isn't available on the strip too, have you?

There also is the technique of completely replacing an ATM in say a mall. Read about that one a couple times. Some ATMs in convenience stores and even retail chains like Walgreens and CVS already look sketchy enough.

How do chips solve the problem? From my understanding, a man-in-the-middle scanner can gather enough information about query-responses to simulate the chip. This was one of the big problems identified with RFID chips embedded in passports because all a criminal would need to do is brush by other travelers with his skimmer.

I seem to recall that some banks (in Estonia??) will mail you a piece of paper with a list of single-use PIN numbers. Use one, mark through it. When you get close to running out, they mail you a new list.
