RFID Blocking Shield CardCredit and identification cards now have RFID technology embedded into them. Most newly issued Passports have RFID chips in them. The chip contains all the data that is on the first page of your passport including your photo. Even your driver’s license can have an RFID chip.
Identity theft via RFID readers is growing. You can protect your personal data with the use of RFID blocking wallets and RFID blocking passport covers. These items contain a metal fibre mesh that makes a “cage” around the chip that radio waves cannot penetrate.
So, lets just look at how an RFID scanner works. The scanner sends out an electromagnetic field, which is used to 'scan' for information.
Now, in the case of our Faraday Shield, this electromagnetic field being sent out by the scanner ends up being distributed all over the exterior of our shield, which then cancels out any charge or radiation from within the shield's interior. In essence, a Faraday Shield is like a hollow conductor in which the charge remains on the external surface of the shield and never actually goes inside.
This phenomenon is often used to protect sensitive electronic equipment against external radio frequency interference.
So when a wallet is acting like a Faraday cage, your credit cards are going to be safe and sound within and no data is going to get out. Some of the most common RFID-blocking wallets are made from Carbon Fiber, Aluminum or other similar conductive materials.
To prove this, lets just see how an RFID-blocking wallet can safeguard your cards.
