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 great

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.

perfect protection

Idk how to test them and see if they really work. But it fits in my phone card case fine.

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.

Small pack of credit card size and seem to work,,, was able to "try" them out at the store using the RFID card near the card reader and it would not read my CC.

Very convenient for the price, glad to get rid of the individual sleeves for magnetic cards.

Have purchased two packs and given them out to friends and family. I feel safer knowing this helps prevent illegal scanning of my credit cards by identity thieves.

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.

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.!!

Already in use. Nobody will steel me again.

Buen producto, rápido envio
