5 Pack RFID Blocking Card Contactless NFC Credit Card ID Protection Safe Bank Card Passport Entire Wallet Purse Shield Protector Blocker Guard (Pack of 5, Black)

Works as advertised! Shared a few with family and friends!

I read all the reviews from others on this product and wanted to try them myself. . I got this because going out of state makes me nervous to have my cards not protected. So I got my order, and to try to see if they worked I checked out at the register and held them close to the cars reader and I have 2 of them in my wallet because it's a big wallet and it was declined! I had it about 3-4 inches away from the card reader. ! So now I feel so much safer by having these. I would definitely recommend those to anyone! I loved the price for 5 of them!! Can't go wrong by having extra!

I was a little leery about this, but tested it out at a local ATM. I placed it behind my card and used "tap and go" on the ATM machine. The credit/debit card had direct contact with the machine, but I got a warning "multiple cards detected" and it wouldn't accept the card. I tried it again with about an inch of space between the credit card and the RFID card (again the RFID card was spaced behind the credit card) and got the same thing. Once I separated them completely (one in hand, the other back in my wallet), the credit card worked normally. Overall, I'd say it's doing something. The only way I know to test if there is some type of circuitry in the RFID card is to x-ray it or microwave it for a few seconds. If it sparks in the microwave, it had circuitry inside and is now burned up. I bought enough of them, so I may do that someday. Overall, I feel these work as advertised.

Easy to use and hopefully blocks the bad guys. I have no idea if it works. If someone tried to "read" my credit cards and failed, how would I know? It's insurance against the possibility of an intrusion. The cards are cheap, sturdy and easy to use. Inexpensive insurance.

I can only assume they work as they should because I don’t have a way to test it. But I feel better knowing my information is protected and can’t be scanned. The quality feels good and fits in the card slots just right. The price was good.

This actually gives me a sense of security in mind. Love them!

I did an experiment with one of these blockers, put it between my CC and a scanner at a POS transaction, and it seemed to work to block the scanner from reading my card. Once the blocker was removed, the scanner read my card as expected. So I believe these cards will do their job! I have a stack of various cards in my wallet, and I placed one blocker on each end of the stack.

Why did you pick this product vs others?: My fault that I thought these were sleeves to put the card in so now I have double "cards" in the pockets of slim wallet. I dont like that. Was not sure if it had to go a certain way but in re reading it - it just had to be close. The cards are not slim they are thicker than my credit cards. not by a lot but none the less. Hopefully it protects.

Hasta ahora puedo decir que la tarjeta de bloqueo funciona bien. La he probado en diferentes ocasiones y evita que la TC se lea. Esperemos siga así.

Good product fast delivery works well will buy off you again thanks

This is an excellent product to product your bank card, credit card, id card or passport from getting scanned. I am going to give to everyone on my Christmas list.

With all the scamming and scammers that are out there as I text, I guess the more security I have for my hard earned dollars and my credit cards I don’t want anyone having access to it except me. I think you will all agree that spending $17 dollars to give your cards some security is a low ask.!!
