The data on RFID cards, whether it's PayPass or payWave, in terms of the data you could get off the cards, is unusable to conduct a transaction. You're only getting the card number and the expiry date, and you need a lot more than that to actually complete the transaction. There are a number of dynamic security features that are missing from that data.
We are aware that there is a gentleman walking around selling his product who purports to have a sleeve that can cover it, which is self-serving: that data cannot actually be used to complete a transaction online or face to face, and you cannot counterfeit a card with that data either. It's rudimentary data that you can't turn into an actual transaction.
