    Default RFID

    Does anyone know if RFID technology can be applied to credit card fraud?

    What do you mean? Do you mean if someone can still scam your card by stealing the info from the RFID chip? They would have to be really close to your card but it is possible.

    If you have an Amex Blue cash card which is probably the most popular card with the RDIF chip, I hear you can deactivate it by putting the card between two pieces of fabric with concrete underneath and then whacking it with a hammer. This breaks something supposedly inside the chip but doesn't change the appearance of it. Just make sure you use those sheets of fabric on top of the card otherwise it will get all scratched up.

    I've talked to someone who claims to know what he's talking about, who says to prevent RFID to be used to get info from any card, including a passport, simply put another RFID card next to it and it will scramble both cards.

    This is the first time I am reading this thread and that's a very interesting question.

    It sounds as if having two different cards together may scramble, but I would guess they operate on a different combination of frequencies. Much in the same way that two cordless phones would not be scrambled if they were placed close to each other.

    Again, I asked my brainy source and he said that cards with RFID chips in them are covered on one side with a very thin layer of alluminum. This prevents electrostatic waves from "escaping" from the card because they can't go through metal. That's why putting two cards together provides security from them being read by an unauthorized machine.

    The waves from phones are electromagnetic and can go through metal.

    I hate those damn computer chips on credit cards. I got card with that on it and I pulled out my Leatherman and ripped that baby right outta the card. No one even uses those damn things anyway dont know why they put em on there in the first place.

    How would you know if you had one in your credit card? Why are they even in there?

    You can see the chip on them. They all look like a big square thingy.

    Apparently there's a whole line of RFID blocking wallets if you want to be really sure you're safe. The sell them here DIFRWEAR

    I've never seen the actual chip on the Mastercards. Any card with a logo like this has one:
