Keep your RFID card's personal information safe
What is RFID Blocking Card?
The blocking 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.

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’s 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.
