  Is it really more broken than just having to sign?

    Fair point, "as hell" was unwarranted. I mainly just wanted to post that PDF tbh.

  It's not that broken. It's still not trivial to clone them like swipe cards. The thrust of that paper is that using special equipment it's possible to use a genuine stolen card to do a non-PIN transaction, and that banks will often claim that PIN was used in a card-present transaction in order to avoid refunding money. In the UK at least, and with a credit card, the bank is legally bound to return the money pending investigation, regardless of the circumstance. (I agree this doesn't help with the BTC situation because chargeback is still a possibility)
