These work! Very simple way to protect you cards from scammers! I tested my card at the checkout with the sleeve on and the reader could not read my card. Took sleeve off and it worked as normal. Recommend this product!

I guess they work and provide protection for your credit card(s). You can’t test them so you just gotta have faith! The only thing that none of us like (cause for four stars) is it’s kinda difficult fishing the credit card out of the protective envelope. It’s not a deal breaker but could be better. They do fit in your wallet or purse easily and are reasonably priced.

Great product, easy to use, it fits in my wallet as well. Definitely recommend this product!

I saw the ads on TV for the fancy RFID blocking wallets but didn't like them. They looked fat and clumsy to me. These little sleeves add practically no extra thickness to your wallet. They're just a hair larger than your credit card. You slip your card in the sleeve, and the sleeve in your wallet. Simple as that. I held my credit card inside one of the sleeves up to the supermarket scanner, and nothing. Crickets. It didn't read it at all. Slid the card out and BEEP. Comes in a ten pack and last quite a long time. Some frayed edges after a while from sliding the unit in and out of your wallet, but that's to be expected. I highly recommend this product.

Be careful since these work almost too well! I placed my car key fob in one of these sleeves. If my car detects that I accidentally left the key in the car, it won’t lock the doors. Unfortunately, the sleeve works so well that the car did not detect the key and… guess what… I locked myself out of my car. Bottom line is that they definitely work.

I dunno, 5 stars for a paper envelope? They do the job of protecting important information from evil-doers with scanners. They also help protect the cards in them. Well, I had fun decorating some of them with hubby's favorite childhood cartoon characters by putting them through our color printer.
