The listing, 2 RFID Blocking Credit Card Pouches has ended.
Every day more and more Credit Cards are coming with embedded RFID computer chips. Also known as Radio Frequency Identification Chips.
These chips allow people to simply wave their credit cards close to the reader to pay, rather than digging though a purse or wallet.
An RFID chip works when an RFID reader sends out an interrogative signal which powers up the chip, which then broadcasts your credit card info.
This is how they project that some day you won't need to remove your groceries from your cart. Everything in your cart will have an RFID chip, and the register will just read them.
Well, this convenience is a double edged sword. You don't need to pull out your credit card with these, you just need the chip close enough to the reader.
Close, like the person behind you in line, someone touching you in the elevator, bumping into you on the street, etc!
The RFID chip is a little radio station anxious to broadcast your credit card to any reader within its range. And the thief's reader can be active, and actively requesting CC info, or passive, silently listening for a chip to spill it's guts during a legitimate purchase.
These pockets are made from a material that will block the relatively weak signal the RFID chip emits. Meaning that any potential thieves with RFID readers will be locked out of your credit card info. It works just like a steel structure with a radio inside. The metal of the structure blocks the signal.
