    Step One: Return the wallet!

    Step Two: Go to Wired.com or Engadget and find one that will block all RFID scans of the encased cards !

    Basically, what you're looking for is a "Faraday Cage" to keep your RFID treasures in ! Various cards use different levels of "protective encryption " but the best/surest bet is to make the cards unreadable except at the time of use. Yeah, I know it ain't a "perfect solution", but educated your lady/yourself not to "pull the card" until you need to, and return it to safekeeping asap !

    FWIW, always "shield" your card(s) from casual observation and immediately clear the screen after your purchase, too ! Be especially wary of anyone using a cell phone in the checkout line ! IOW, think of any credit/debit card as your net worth on public display ! >MW

    copper fly wire is THE best at blocking RFID but connect it to a LED so the energy ( while not enough to light the LED ) will have a place to run too

    thats from a bloke here who's a expert at such things
     
  5. 3 minutes, high power in a microwave works for me but then I am kind of a grinch when it comes to that kind of thing.

    If a picture ID, and cash isn't good enough for them then to hell with it.

    Go find some brass screen stock and cut a few card sized pieces for your wallet. I got the idea from mythbusters. they built a box the size of a phone booth and walled in nothing more than brass screen. It killed all electronic signals. Cellphones, radio, CB, etc. etc. etc. I cant see a scanner that reads stored electronic data being able to scan the data thru an uncompatable material. So I have 3 brass screens in my wallet. I cut 1 for each fold, and my wallet is a trifold. Put them toward the outside. and the inner ones help jam the recieve of the scanners im sure.

    Ok, for some reason it hasn't set in until now. I have access to rfid chips and readers, all day at work. I'll do some research
