Product Q&A

Q:Why do I need an RFID blocking card?

Hackers use scanning devices to capture card numbers and vital details from identification chips. Our card blocks this access by transmitting white noise, making your cards invisible to hackers.

Q:How does the blocking card work?

It instantly creates a surrounding electronic field that makes all 13.56MHz cards virtually invisible to RFID and NFC scanners.

Q:How many cards can one blocking card protect?

The protection field is about 2-5cm. If cards are placed together, one blocking card can protect approximately 5-10 pieces.

Q:How should I place the blocking card?

Place the blocking card directly in front of or behind the credit cards, or simply place it together with them in your wallet.

Q:What materials are used for the card?

The card is made from PVC, PET, or PETG materials.
