RFID safety done actively not passively.
Great security at a great price. These work exactly as claimed. I tested using my cards with these blockers near and they effectively block their use.

Feeling more secure!
I've read that these types of products can help with criminals accessing credit card data even while your credit cards are in your wallet. I was the victim of identity theft in 2021 and have reason to believe that two of my credit cards were compromised while in my wallet, because within two hours, I started getting hits from two cc companies that some charges were appearing. CRAZY. I got the three pack of these so I could put one on each side of the pocket that holds my credit cards. My current thinking is that you can't be too safe, and for the low price of these cards, I thought they would be a good investment, and I'm happy I've got them.

Fits nicely into my wallet.
Never really tested it, so I don't know how effective this is.

Works
To test it, I went to a gas station and where you tap to pay on the pump. I first tried it several times with the Block card on top. No matter how many times I tried to pay it didn't work. So then I tried it with out the Block card and it worked the first try. So it seem to work well.

Protection Card took a while to arrive but that was expected at time of order. Have checked that the card blocks blocks your payment card details when paying for goods. Hopefully this card will keep my details safe.

The product does not work. I tested it by holding it against my credit card and using it to make a tap purchase. The RFID card reader read my credit card perfectly. Going to try card sleeves next.
