RFID Blocking Sleeves Contactless Cards - RFID Credit Card Protector Waterproof and Tear Proof - Debit Card Protector Sleeve for Privacy and Property Safety by Defender (5 Pack)

The sleeves are fine but they need a design review. I had to cut one side in order to easily slide the card in. Without the cut it was almost impossible to find the "slot" the push a credit card into. Now that I've modified the entry they are easy to use. You can simply leave the sleeve in your wallet and just slide the credit/debit card in and out - AFTER you have cut the slot!

These envelopes seem sturdy enough for a bit of wear and tear. Time will tell but I do think more publicity should be given to the fact these envelopes also protect cards with a magnetic strip from damage from Magnetic clasps on purses and bags. Also key cards at hotels which also have magnetic strips. On a recent holiday our key cards kept being rendered useless until I remembered being told that magnetic fasteners on bags can damage them and also debit/credit cards apart. Once I had put the key card in one of these envelopes it didn't happen again. So apart from preventing cards from being cloned in one's pocket or bag they have another use.

Light, handy, & hopefully effective. The only drawback, is after you take your card out if the sleeve, to use it, it is very hard to get it back in again. The sides of the sleeve stick together, & it's almost impossible to squeeze it back open to put the card away, which is not what you want to be doing, messing about in public, with your card in your hand, trying to put it away.I have started to keep one finger in the sleeve when I can, so I can keep it open, so the card can be put away quickly after use.

Bought these after a friend had his card read by someone bumping into him whilst the card was in his pocket. Then in a few minutes his card details were used for 5 contactless purchases under the £30 limit.... booze & cigarettes, before the bank stopped his card due to suspicious activity. Impossible to know if these work or not but decided to trust them for the small cost involved. I found them a bit fiddly to use on each card so now I have the either side of cards in the slots in my wallet

I did not want a separate 'protection' wallet to keep my cards in so thought I would try these sleeves.It is a bit difficult to get the card in to start with but OK now. I put the card in with the scan sign at the top and which means you do not have to take the card out fully if scanning. When the cards are in the wallets they still fit into the credit card slots in my purse.

These sleeves do exactly what I bought them to do, protect my bank card and other cards from being used on chip and pin once they are in the sleeve. Good security for all my cards. If I had a slight complaint it would be that my cards don't slide in the sleeve as easily as I'd like, it's a bit of a struggled if your hands are full. Still worth purchasing as they do what they are supposed to do.

These card defenders are brilliant, working to keep your money safe from scammers. i have tested mine a number of time at the checkout and it wont make a payment while still in the defender wallet. They are very tough ,don't rip or break ,i feel a lot happier knowing they keep my money safe.

These fit cards in well and are easy to fit into a wallet or purse. However, putting cards back in takes two hands and bit longer than just slipping them back in your wallet used to. So a bit fiddly but hopefully worth it for the protection.
