Contrary to what you may have been told, the phrase "RF ID" does not stand for Red Freckles Indicator. Maybe you already knew that because of the times you had to wrestle RFID tags off of your newly purchased clothes (the size of the hole in the fabric determines who won that match).
Now, these micro-miniature radio frequency tags are making their way into everything just to scream out to the world what it's attached to. If you're in Las Vegas, poker chips are embedded with these little marvels, ready to announce to the gambling establishment (and probably the IRS) how much you won and when.
At the gas station, the gas pump sits ready to listen for your new fangled credit card to broadcast your account number. Unfortunately, thieves also listen for this most private of transmissions. While they don't dress themselves up as a gas pump, they do sit concealed in their electronically equipped vehicle nearby.
There are solutions to protect your rfid credit card. One method that I have wondered about involves wrapping your entire body and wallet in those extremely thin and flexible sheets of aluminum. If a thief then sees you after he realizes that he can't get your vital data, would he say, "Curses, foiled again!"
