16 RFID Blocking Sleeves Set (10 Credit Card Holders & 4 Passport Protectors) Identity Theft Protection Secure Sleeves Set.Waterproof aluminum foil slim Design easily into your Wallet

Though it's said passports are protected "to make it difficult" for perps scan it, I think it's good to err on the side of caution and keep it in the RFID sleeve, which also keeps it clean, etc. Passport CARDS -- Like Credit Cards -- AREN'T protected! The differently colored sleeves are perfect, and easy to know which card is in which color. These are Really Good To Have On Hand (ESPECIALLY for the price!) even if you don't travel a lot or leave home with credit cards all the time. There are also enough passport holders to share with someone else!

Bought two packs and handed them out to friends, keeping 2 for myself. Do they work - I don’t know but I haven’t had a problem with credit card data being stolen so I have to trust that they are helping to keep the bad guys away! They fit the standard credit card, simple to use, and take up no space. Price wise they cost very little .good deal.

These are handy protectors for all our RF cards - definitely worth the purchase, especially if you've ever had a card skimmed because you were carrying it, unprotected, in your pocket. We now have all of our cards in these blocking sleeves. The bright colors make them easy to spot in my wallet, too.

I bought these 2 months ago. They are still intact, haven't torn, and are thicker than some others. I used the NFC feature on my phone to see if it could read my card in the sleeve. It didn't show anything. I took it out of the sleeve and it instantly read my card. I also need to remove the sleeve so it can be scanned at the cashier's touchscreen checkout. I am not sure what its actual description name is but until I remove the sleeve it doesn't do anything. I feel comfortable with those results and can confidently say that they do work. I gave it 4 stars because they can be difficult to insert cards into and fit very snugly in my wallet slots, which can be challenging to put in and take out. Though, I would buy again.

These are so much nicer than the early ones which came out years ago. The quality is great, the slide in and out of my wallet easily and I feel so much safer.

As far as I know they work well! It makes it easier to find the cards in my wallet also. And they make a great gift

Great and colorful RFID blocking sleeves

Because of how they are made, they are too wide to fit in the slots in my wallet. I am going to try trimming them and hope it doesn't mess them up.

This item was suggested as the way to protect credit and debit cards from scanning by thieves.

Worked well. Good value for money

They work, and massive variety of colours

Great service prompt good price and exactly what was ordered

Look great. A little tight to draw yr cards from and a little harder to reinstate them. Hopefully they will loosen up after a while.
