Product description
RFID Blocking card-The RFID card is the size of a credit card that is designed to protect personal information stored on high frequency (13.56mhz) smart cards such as credit cards, debit cards, identification cards, passports, membership cards and so on.
The blocking card needs no battery.It draws energy from the scanner to power up and instantly creates an E-Field, a surround electronic field making all 13.56mhz cards invisible to the scanner. Once the scanner is out of range the blocking card de-powers. Simply carry this blocking card in your wallet and money clip and all 13.56mhz cards within range of its E-Field will be protected.
If your card is contactless enabled, your card holds information within a chip. This chip also contains an antenna that picks up power from a signal sent out by a card reader. The card reader and contactless card are then able to communicate on a 13.56MHz radio wave signal when in close proximity. This is great for convenience, but not so great when low-life criminals have a scanner……
Fortunately, there is a very simple way to keep your identity and information:RFID Blocking Card/RFID Data Shield Card/RFID Anti-skimming Card. Simply place one card in your wallet and all surrounding cards are protected.
The RFID Blocking card works by drawing power from the scanner, and emitting a counter-signal to jam the communication. This protects the surrounding cards within a 5cm radius (roughly). It is the same size as a standard credit card so will fit in any wallet. It is however slightly thicker, at 1.2mm VS 0.76mm of a normal card. This is due to the internal circuitry.
