Depending on how thick you keep your cards, I actually just put mine in the middle and only have 3 on each side and it covers all of them without an issue. Been using this brand for a couple years and still haven’t had to change the card either, highly recommend.
You definitely can, but I only use one in my leather wallet and it does the trick. If you want to be certain to obstruct any signal leaving your card holder, place one on each side of your cards. Hope this helps!
The only thing I can think of is you’re placing the reader on the Flipper to the side of the card. Every time I’ve tried to read any one of multiple RFID or NFC cards, these have blocked the signal.

That’s a great tip! Will give it a test with the Flipper to see how it goes. Thanks!
Can we use 2 to be safer? I use a card holder with both ends open

I experimented extensively at the grocery store, only one card in any position is all that's needed to protect the whole wallet.
Do we need to remove the cellophane the card comes in or does it matter?
The RFID blocker will still work with the cellophane, but it serves no purpose other than protective packaging so can go in the garbage.
this doesn't work against basic tools like flipper zero.
🤔 I literally show you how it works against a Flipper Zero in the video.
@@paulysproductreviews I tested this with my flipper and was able to compromise it. Maybe your card have had a revision since 2023?
