Crystal PalaceRFID/NFC Contactless Blocking Cards Protection |Credit and Debit Card Protector for Men and Women| Crystal Card Guard | Protects Passport, Wallet and Purse from Scams.

This little gadget is amazing my friend at work was demonstrating to me how easy he could scan from my card via contactless and being close to me I was surprised when he showed me but not anymore since I got this card he is surprise he cannot do that anymore I would strongly advice anyone who is concern about their cards being protected this is a must have card in your purse it is very simple to used and gives you peace of mind

My brother got me this as a gift and boy, does it work. Actually, I found out at a supermarket when I got rejected 3 times before I realised I had my wallet a little too close to the machine! In another shop I had to put the card behind my back before I could pay. However it works - it works. Brilliant. Recommend to anyone.

A nice idea, a credit card size contact blocking protection but there is no way that one can check to see of they actually work, they use power from the scanner, I haven't a clue how to check their effectiveness.

Well think it’s good. Nice quality card. Hopefully works, but really, wouldn’t know. Lol

this product is fantastic, I have even tried it to pay contactless holding it slightly away from the machine and it bounced. The card fits perfectly into my wallet slot and will recommend this product to other, in fact, I'm going to give them as a gift to friends.

I tested the card against a retailer's contactless reader and the blocking card worked very well. It gives me the confidence that I will be protected against the opportunist fraudster.The convenient standard size fits in my wallet without any problem even with the small increase in thickness.

I put it in my wallet, does it work know

Slim just like normal card
