RFID Wallet CardShield Real Customer Reviews At its core the RFID Wallet CardShield uses layers of conductive materials—aluminum alloy, carbon fiber conductive cores, metal-infused fabric, and steel—arranged around the card cavity so that when RFID-enabled cards are placed inside the RFID Wallet CardShield, incoming radio waves are absorbed or reflected rather than penetrating to the card chip. This function creates what engineers call a Faraday cage effect, and because the RFID Wallet CardShield is designed to block signals across a wide frequency band (approximately 10 MHz to 3000 MHz) it specifically targets the 13.56 MHz band used in most contactless credit cards, transit cards, and identity documents; therefore, when your cards are inside the RFID Wallet CardShield they are insulated from the signals a skimming device would attempt to use. Practical notes about how the RFID Wallet CardShield interacts with access control systems are important: because the blocking is effective, many building or office access cards that rely on 13.56 MHz signals need to be removed from the RFID Wallet CardShield for legitimate scans to work, so buyers should expect to temporarily remove access cards when entering secure doors; the RFID Wallet CardShield is doing precisely what it’s meant to do when that removal is required.
