INNOVATIVE HAUS RFID Blocking Card - Slim RFID and NFC Contactless Debit and Credit Card Protector for Entire Wallet and Purse - 4 Pack

So far so good

Well, I haven't been hacked yet, so I guess it works

I was shopping at a local market and was checking out at the cash register and know the owners I wanted to see if it really works so I put the RF card on top of my bank card and the scanner couldn't read it. Then I tried it on my credit card and it couldn't read that one too. When one of the owners saw that she asked me where I got it, so naturally told her Amazon, she told me she was going to order her some of these cards right away!

RFID cards received promptly promptly and oder was conplete. I haven't had a chance to test them yet.

Well made. Price is right

We bought two of these packs of four RFID cards and shared with our kids and grandkids. One can’t be too careful these days. Let’s hope they work the way they’re supposed to!

I thought these were "sleeves" to put my important cards into....however they were actually like cards themselves. Personally, I prefer the "sleeve" style, over shuffling these protector cards to the outside of my important cards.

Great
