Why Do You Need One? 
A BBC report recently showed how thieves can walk through a shopping center and gather contactless credit card details from over 50 cards 
in less than 20 minutes simply by walking up close to people with a scanner. Credit & Debit Card fraud has risen over 31% due to wireless theft in recently years. 
Protect your money, identity and information safe

How Does It Work?  
The RFID Blocking Card is the same size as a standard credit card and 0.03inches thick with built-in internal circuitry. 
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 2 inches radius. It can stop transmissions of personal information to a remote RFID device. 

How to Test if It Works... 
There are several ways to check if your card works just in case you want to be sure. The easiest way is at a self-checkout at a local supermarket. 
Place the RFID blocking card on your contactless card and bring them close to the contactless card reader. 
You will find that the credit card cannot be read. 
This shows that the RFID blocking card confused the scanner and is working as intended.

What does TICONN Card signal blocker work with?  
The contactless card Works on 13.56MHz frequency. This includes, but is not limited to: 
--Debit/Credit Cards
