wisdompro 6 Pack RFID/NFC Blocking Cards, Credit Card Protector, Contactless Card Protection, RFID Card Blocker for Debit Cards, ID Cards, Passport, Wallet & Purse Shield - Blue

Good value and work well

I usually by the sleeves but due to husbands wallet not having built in protection I opted for the cards. Arrived quickly and neatly packaged. Feel robust,sturdy opposed to floppy cards.Was concerned other reviews indicated they set off shop alarms. I immediately put them through a multiple shop test and relieved alarms did not go off at all. Big thumbs up from me.

I guess they do the job, I’ve had no questioning in my account.

Just what I was looking for. Thank you.

The price for the amount you get is good so you can use one in either side of your wallet to be doubly sure your covered! Slim profile and good colour, same size as a regular bank card. Tested it and works fine. Good job.

Arrived fast the same day 6 cards in there own case and individually wrap . Enough for both mine and the wifes cards , makes you feel safe and secure,well worth the small cost

Put 2 of these in my wallet & tested at a contactless till, they work very well

Review updated 30/09/23 - after using the cards for a few weeks I've had to stop using them. They were setting off alarms on security scanners when entering as well as leaving stores including supermarkets. The fact that this happened on entry to the stores eliminates the possibility that tags were accidentally left on purchases, also it was happening repeatedly.Original review:These blocker cards are the same size as credit or debit cards & so will fit in the slots in a wallet or card holder. They're well made.They do block NFC/RFID signals. To verify this, firstly check which credit/debit/other cards support NFC by scanning with a smartphone. This involves enabling NFC in the settings and using an NFC reader app.Then place one of the blocker cards in a slot at each side of the wallet or card holder (with the other cards between them) and try scanning around the outer surfaces when it is closed. If the app doesn't detect the credit/debit/other cards now then your cards are safe from snoopers.

A cashier allowed me to experiment to see if it truly blocks the RFID and it did. Holding the card below my credit card, the credit card reader could not read my card. It was nice to actually try it like that so that I can rest assured that they really work as stated.

While I was buying two wallets that claim to be RFID blocking from Amazon, I also picked up a set of these and also re-ordered a second set. The small wallet for my personal cards had a card insert that said so it was RFID blocking, but the larger wallet for ID and house cards from a different vendor did not mention this except in the Amazon ad. I decided some RFID blocking cards would also be extra protective. I have 2 in the small wallet to guard whatever is in between. I have 3 set up in the larger wallet since the cards fit in at different heights and on 4 different areas in the wallet…it opens like a book with a page in the middle and there are slots on both sides of the page. I also noted that the card will protect what is immediately in front and behind for a limited distance (see ad pictures) which is the reason for the 3 cards set up at different heights in three of the sections in the wallet. Probably overkill, but people are becoming more sneaky and there are apps to help them with their criminal activities too.So I did test one of the cards at the grocery store. I let the cashier know what I was doing and why. (She had no clue that people could read data from your wallet and steal it.) So I place the RFID card over the Bank card and tried tap. No reading. Removed the RFID card and tried tap again…transaction went through. I was sold. Ordered a second set so that my DH could have some for his wallet (He informed me he had some sleeves. First I knew that he was already guarding his ID. Hmmmff!!!) and some for some friends who we will be travelling with during the summer.A valuable purchase. Do place more than one in your wallet especially if it a complicated design with multiple areas for card storage. And make sure that others become educated regarding identity theft.
