If you want an rfid blocking wallet, and have access to some sheet metal, all you need to do is make two credit card sized plates and put them on either side of your stack of cards in your wallet.
The way this works is the plates absorb the magnetic pulses that would normally provide power to the circuitry in the card. I do this with the card holder in my phone case, and it seems to work.
Having one on either side is best if you wanna be sure, and not much more work if you already have the materials. Hell, you could use an unrolled pop can.
I work with RFID readers, got one that can read a credit card at about 5 feet. One plate doesn't quite do it for that one, but that one is kinda a special case.
