RFID Blocking Card | NFC Contactless Cards Protection | 1 Card Protects Your Entire Wallet | No More Need for Single Sleeves | Credit Card Holder, Wallets or Passport, Men, Woman - 4 Packs / 8 Cards

I don't think this protects your cards. I have one in my wallet yet I'm still able to open the door to my apartment building using my keyless entry card fob straight from my wallet without taking it out and away from this RFID blocking card. I'm also able to do the same with my metro card at the station gate. This leads me to believe this card isn't protecting my credit cards and my identity. I don't recommend.

If I could give this product no stars I would ~ went in to my local grocery store and placed the card on top of my credit card as I pushed it in to pay (to see if it really worked) and the charge went right through with no problem whatsoever. I couldn't have placed the Blocking Card any closer to my credit card, yet still the transaction went through as if the supposed RFID Blocking Card was nowhere near it. The only good thing about this whole experience is that I checked your product out and revealed it didn't work before travelling with my Passport believing it would protect my Passport.

First let's clear up 2 things... 1) if you test this with your work key card or similar, it will not disable that type of card -- that is a different frequency than what is used in the RFID credit cards. 2) The RFID card is a credit card that has TAP to pay capability - that is what this card protects from being stolen - not if you swipe the card somewhere that has an illegal skimmer on it and your information is skimmed by that means.This is how I know it works: I have only 1 of these blocker cards in my wallet. I was trying to complete a transaction yesterday (with a card that has RFID tapping capability), and as soon as I would insert the card, tap or swipe, the transaction just would not go through. It wouldn't do anything except tell me to insert/tap card then remove card. After 3 tries, I realized I had my wallet sitting on the counter about 3 inches away from the credit card machine. I moved my wallet farther away, and my card instantly worked to pay for the transaction. This blocker card apparently does send some type of signal to trip up anything that is attempting to read your RFID credit cards.I have had this same credit card stolen from me locally when I hadn't used the card in months. It have to have been stolen by someone who was able to get close enough and skim it with an RFID reader. Thankful to have found this blocker card because it gives me a little more peace of mind with all the thieves we encounter these days!Edit to add: this card being in my wallet deprogrammed a hotel key card. Not once but twice on the same trip so I would not sit your hotel key card next to this. I have had some Apple Pay machines not process that type of payment as well even if I put my purse behind me. I would have to have the blocker card at arms length away from the machine to get Apple Pay to work.

So at first I wasn't sure how to rate this because I didn't know how to use it. But when I went to the gas station and I used my debit card and the machine read "card error" and I couldn't figure out what was happening until I realized I had this in my pocket and when I put the blocking card in the car and used my debit card again, IT WORKED! So BOOM. I just knew I had to review it because now I knew it works!

I read the reviews and these seemed promising. Some of the reviews I saw said they were not sure if these things did anything. For the cost, I thought I would give them a try.There are key card locks where I work to get into the doors. I put one of these cards in front of my key card and it worked. I could not unlock the door. Then I tried putting the RFID blocking card in back of my key card, facing away from the sensor and tries it again. The first 3 or 4 swipes did not work, but as I tried swiping my card in different ways, it did unlock one time.I put both cards in my wallet one on each end so that my banking cards are in the middle. It seems to work well.After some time of using these, I will try testing them some more. If there is a different outcome, I will add to this post.

Product seems to work as described. I have had my cards compromised before and cannot stand for it to happen again. I tested it at a checkout and it blocked my card from being read by the machine until I moved the RFID protection away.

I bought these for my Citi Costco VISA card which has the RF transducer inside (where you just tap it on the credit card reader to process). With this card anywhere near the VISA card, when I tapped the credit card reader, it came up with an error because this blocker has a transducer in it that transmits a jamming signal so the credit card reader can't get a proper signal from the credit card. Yes, it works as advertised.

Very disappointed this is non-refundable. Buyer beware!!!
