Credit Card RFID Vulnerabilities

This looks like an interesting paper published recently about the vulnerabilities in RFID chips found in newer credit cards . It sounds like the issues are fairly serious — all card tested were found susceptible to privacy leakage and relay attacks, and some of them can be “skimmed, and replayed at will”. These can be combined with “cross-contamination attacks” by encoding related data to the magstripe of the same card.

I personally never saw the point of these RFID CC’s. I guess I don’t get the difference between swiping your card <10cm away vs. swiping the magstripe directly. Is there some other grand use case for these that justifies the risks involved?
