A company called Taiyo (located in Shibukawa city, Gunma prefecture) recently developed a super thin (0.4mm) credit card size device for skimming protection. Consumers put it on top of RFID cards to prevent the cards from secretly read by strangers etc. It's called "Skimming Card" (though I would rather call it "Anti-Skimming Card"). What's interesting about it is in how it works -- When (Anti-)Skimming Cards are exposed to electro-magnetic fields created by RFID readers, they create excess electric current in it and actively create "reverse" electro-magnetic fields that is approximately the same strengths as the readers' fields, thereby, prevents RFID readers to read RFID cards.
We can relax now:-)

I have just found this.. I also posted it in the corresponding ISO 14443 thread... www.cl.cam.ac.uk/~gh275/relay.pdf

I am asking a Japanese friend to look for me... but I guess as mentioned by kf6auf, probably a bit of foil around your wallet.
Once you take the card out of the wallet... well... make sure you keep it foil wrapped...
time to buy shares in foil companies
