Each RFID Blocking Card is designed to be able to protect 2 NFC-enabled credit cards (13 MHz RFID) – one card in direct contact on each site. The Blocking Card can also be used as a privacy card to block view of your ID and credit cards while in the DM1 Wallet.
Please note that our privacy card was specifically designed to NOT fully block 120 KHz RFID signals (it may decrease the scanning range for these cards) – this frequency is most commonly used for building / door access and government / company ID cards. This allows you to still use your key cards while inside the DM1 and still protect your NFC credit cards.
Please note: Each RFID Shield card has one glossy side and one matte finish side.
