Why not just buy pre-paid VISA cards [ed: and even if they do -- the damage will be limited] ? AFAIK they don't have RFID? I'd be more worried about my passport (if it had RFID).
And no more RFID.
Edit: As a frequent (if reluctant) traveler, I've yet to encounter a necessity for RFID at passport control. (I simply avoid that particular queue.)
I've been stopped twice for not being obedient: once because I refused to step into a mm-wave scanner (after the controller refused to send me back through the metal detector after I removed my belt...), and another time for not staring into the hypnotic blinkenlights that were swirling around the cameras above everyone's heads in the queuing area.
