Really? This is predatory marketing based on fear and ignorance. If you know anything about RFID, you know that a piece of aluminum foil performs the same function as this "armor". These cards do not "radiate" signals, as their radio advertisements say, unless there is an active antenna and reader nearby. And by close, I mean a few inches. Spare me. If you need security, don't use an RFID credit card, use cash instead.
