    Maybe make a duck tape wallet but add some layers of that copper fabric Adam used in the "Gun to a knife fight" episode of Mythbusters? You'd just need to make sure the copper completely surrounds your cash, cards, passport or phone. I think a good way to test it would be to turn on wlan on the phone, connect to your local router and then slap that sucker in the wallet and see if the router can still find its mac address.

    RPI Polymath has some instructions on making a duck tape wallet. For the copper fabric maybe just use a 2 side tape out the outermost skin and then tape the fabric to that. Make the fabric a bit longer all the way around so you can sew a metal zipper in. I'm not sure how well it would work, so definitely test it afterwards.

    Roll your own! The duct-tape wallet made out of foil duct tape, with an extra flap to cover any RFID cards.

    It's actually better designed than the passport itself!

    http://www.rpi-polymath.com/ducttape/RFIDWallet.ph p I've tested it with a new proximity door access system we now have at work and it does block the signal. Note that you should modify the wallet to create a passport or PASS holder as needed.

  15. Just make one... by SheepHead · · Score: 1 · on What's in Your Billfold?
    A lot of people have posted links to duct tape wallets. They are pretty decent. It is a lot cheaper to make your own, though. this guy has a great tutorial to give you the concept, and after you build one (or mentally digest the tutorial) it's easy to modify it.

    I made mine smaller than the tutorial version, with fewer pockets and made it slightly shorter to be closer to the size of a US dollar bill. But you can add more pockets or modify the design however you want. And when people say "Is that duct tape?" you can say "Yeah, I made it out of duct tape. It's solid duct tape," instead of saying "Yeah, I bought it online."

    In fact, it'll cost you about $4 for a roll of duct tape, and I made two wallets (a test run and a final run) and still have 90% of the roll of duct tape left. So it probably cost like $0.20 and took about 30 minutes total.

    And you can give it 2 card pockets, or make it tri-fold, or add a window for a driver's license, or whatever you want.
