Nice design & works as it should

It works and it looks good! What else to ask for?!

I've read many reviews talking about how they don't know whether these RFID blocking cards work or not.
Well, they can be easily tested. I tried it on a contactless parking payment machine (you can try it on your next contactless transaction). With the blocking card you cannot make a payment but once it's removed from my wallet I was able to make the payment.

You can use it to protect your contactless bank card.

Note: the blocking card has to be within 2 centimetre of the card you want to protect. Placing it behind or in front of the card makes no difference and there is no need for the cards to be touching.
