What is an RFID blocking card?

 An RFID blocking card is a small, thin card or sleeve designed to protect your contactless payment cards, passports and other RFID (radio frequency identification) enabled cards from unauthorized scanning and data theft.

How do RFID blocking/blocking cards work?

RFID blocking cards consist of a circuit board that disrupts the scanner's ability to read RFID signals. There is a non-rigid coating on the outside and inside, making the card very flexible.

Keep your data safe

With RFID blocking inside the card's innovative circuit board, you can ensure your card number, address and other critical personal information is protected from nearby radio frequency identification (RFID) scanners.

Blocker cards/shield cards do not require batteries. It draws energy from the scanner to power it up and instantly creates an E-Field, a surrounding electronic field that makes all 13.56mhz cards invisible to the scanner. The blocking/blocking card shuts down power once the scanner is out of range.

Simply keep this blocking/shielding card in your wallet and wallet to protect all 13.56mhz cards within their electronic fields.
