Replacement of the Oyster card would be pretty cool, especially for tourists. Assuming they can still calculate the smartest price at the end of the day. How secure is NFC in general? How are these payment systems protecting against someone setting up a fake system to read out CC data?

  Works as an oyster replacement, for 'pay as you go'. Not if you have any kind of travelcard, AFAIK.

Contactless cards have been universally accepted on the London transport network for quite a while – this includes Apple Pay, and I assume Android Pay too. Contactless/NFC has no security in the sense that it requires no interaction in order to charge a card. Security is provided by bank guarantees to refund fraudulent transactions, capping transactions to low-ish values, and requiring a PIN-authed transaction every 5 contactless transactions. Card data cannot be extracted from a transaction in this way, and fraudulent terminals are unlikely to appear due to the need for merchant accounts and the associated paper trail. In the case of Apple Pay and presumably Android Pay, there is the additional requirement that transactions are authenticated on the device (TouchID / passcode for Apple Pay).

Why? I quite like the several anonymous Oyster cards I own - quick to use, easy to fill up (with cash).
