Does the Groove Wallet™ come with RFID blocking? What does RFID mean?

All of our wallets come with RFID blocking. Your cards are safe no matter where you go. Since many modern credit cards are equipped with radio frequency identification technology (RFID) - wireless non-contact use of radio frequency waves to transfer data - there's a growing demand for protection from unauthorized and unwanted scanning of your credit cards. The good news is the outer aluminum alloy shell gives the Groove Wallet™ instant ‘wallet blocking technology.’
