ALPINE RIVERS RFID Blocking Sleeves 18 Pack - 14 Top-Load Credit Card Protectors and 4 Passport Sleeves, 13.56 MHz NFC Blocker, Professional Black

These are a replacement for other worn out RFID sleeves for my credit cards. The quality is impressive, along with the many details, (color and number coding). The choice to slide the card in either direction, depending on the sleeve you choose is a great feature, and I applaud the design team who brought this perfect solution to fruition!! They truly thought of EVERYTHING needed in this product, and have offered it at a reasonable price as well. I would certainly reorder, although, with this quality, I seriously doubt that I'll be needing to do that anytime soon.

Very pleased with the sleeves. Worth the cost.

While they're a little thick to provide the necessary electronic protection, they're not ultra thick and still fit in wallet slots. I tested trying to tap one in its sheath and it didn't read. Good variety of sheaths.

Very good quality and plenty of room for card while still fitting in my wallet

These sleeves work perfectly. I tested them when buying grocers. My card could not be read through the sleeve. I gave some to my elderly parents that had never heard of RFID card theft. I gave some to my wife and daughter. I didn't need the larger size, but I in the future.

Exactly like the picture. Very sturdy

I use primarily the card sleeves. It fits standard size credit/debit cards perfectly (at least US ones), and does not significantly contribute to the size. I have a Crabby Gear Canvas Wallet (non-elastic) and comfortably fits 4-5 cards (not including another 3-4 ID and insurance cards without the sleeves). This is same as before I had the sleeves - and had a card electronically stolen and used on the other side of the continent. When in the sleeve, a cash register RFID reader does not pick up the card - I tried at multiple POS systems - so it does its primary job from what I can tell. I've had these for over a year, and there is no significant wear-and-tear, even with daily use for some of them. I did read some negative reviews here, and to comment on some of those: * Yes, there is a card imprint on the sleeve if the card has embossed card number on it. Many newer cards do not have this. If yours do, I would definitely use caution not to lose them (as with the card itself) and dispose of mindfully (e.g. shredder). * These do not work with security badges. I tested mine with one of the passport-size sleeves to confirm this. I believe the reason is significantly lower RFID frequency than the credit card chips. You may need a Faraday pouch or something if this is part of your threat model. * Yes, it's a bit of a nuisance taking card in and out each time. You have to get in the habit if you want this layer of protection, there is no way around it. To help reinsert the card, I suggest slightly squeezing the sides. On occasion, for example if there is a line behind me, I just put it in my pocket and put it back in the sleeve at the next opportunity (e.g. in the car). * Yes, an RFID wallet can provide better, more streamlined protection (I have one of those as well for certain uses). But, if you like your wallet, as I mentioned above these do not contribute significantly to the size. * Some reviewers commented how the card no longer fits into a single pocket inside a wallet. I used a wallet I have, see photo. With one card per pocket, they go in and out very easily (right side). With two cards per pocket... well, to be honest, the 4th card took some effort to get in (left side). Obviously, it's going to depend on the specific wallet - my wife said she had issues with hers as well. For my use case, the credit/debit card sleeves do exactly what I need: block contactless chip readers, don't get worn out easily, and fit in my existing wallet.

The sleeves easily fit in my purse slots and the indentation on top makes it easy to identify the card you need.

ho trovato queste custodie di varie dimensioni versatili e comode oltre che resistenti visto il materiale di cui sono fatte. Si possono inserire facilmente in ogni portafoglio anche da uomo. utile per ogni occasione ma soprattutto quando si viaggia in aereo o con mezzi pubblici

Ottima protezione, misura giusta per la carte e per inserirle all'interno del portafoglio. Direi ottimo prodotto anche dal punto di vista del materiale. Consigliato

I am not sure if they really work but it was better to make sure that we are protected

Très bon choix, le passport européen entre parfaitement sans pour autant glisser hors de la pochette Idem pour les petites mais ce sont les dimensions standards de toutes les carte de paiement. Le petit 'creux' au centre permet de le/les retirer vite et sans difficulté.

Good product - it works because I tested it - your payment won't go through with this sleeve on.
