Sure it's mildly inconvenient if your CC number gets stolen. But the CC company is the one that foots the bill. In that sense, they are the ones with the best incentive to keep the number secure. If fraudulent transactions instigated by RFID-scanning thieves ever gets to the point where it is a serious concern, I am certain that the companies will act in their own best interest to curb the behavior. In the mean time, who cares if they lose some money?
It is like it was with debit card PINs here in germany, the banks convinced the judges that the cards are absolutely secure so that any fraud was in fact to blame on the card holder who either didn't protect his PIN or was actively trying to defraud the bank.
