Our Blue Sky Basics™ Stainless Steel RFID Blocking Credit Card Holder was tested by a nationally recognized test laboratory in the USA to verify that the RFID blocking capability really works. When the card is outside the card holder, the RFID scanner gets readings from it (indicated by beeping). When the card is inside the card holder, the scanner is completely blocked. Therefore, a contactless RFID chip-enabled credit card, which operates at 13.56 MHz radio frequency, when placed inside the card holder will be effectively shielded from illegal RFID scanners.
