Savisto RFID Blocking Credit Card Sleeves 20 Pack | Contactless Card Protection Holders for Identity Theft Protection - Ideal for Debit, Bank Cards, ID & Key Cards

Seem to work, no issues with the size as they fit in the credit card slots in my wallet.

I purchased these for a planed holiday for extra security.They’re a bit of a tight fit for the credit card slot in your wallet.That said, they are good value

Purchased this as a means to avoid buying a wallet which, has the RFID blocking feature built-in. Because, I have lots of old wallets which are perfectly usable and in this environment - we should all be avoiding throwing away items where avoidable. So, recycling is what I decided to do by purchasing this item and inserting a credit card into it (also fits inside wallets but, I think not all as the sleeve makes the card seem a little larger).Worked perfectly as I tested it out at a self-service checkout till at the local supermarket. The machine could not read the card when in the sleeve.Worthwhile investment to protect the details and money from your bank accounts.

They really work great card security tested them in the local supermarket

I saw my friend with these and he sent me the link. When they came I tested on by putting a card in and trying tap-to-pay and of course it wouldn't sense the card. So bingo... looks like it does what it says and is a very affordable purchase. I gave some to my daughters for their cards too..

If your purse or wallet isn't RFID protected then these are for you. Far too many cards for one person, but they do work. Only problem is that you can't put your cards in the slots, so I've had to just pop a couple loose on purse, although recently found out that my purse is RFID protected anyway 🤦🏾‍♀️

I've been using the same one since September 2024 and I've not lost any money yet.

I felt I needed to buy RFID cover as there are plenty of dubious ppl about. Until I get a nice purse with cover these will be fine. You can get more than one card in each sleeve if needed.
