RFIDsafe™ Blocking Pockets & Material Most passports, credit cards and ID cards now contain a RFID micro-chip. This chip contains all your personal, sensitive information. Identity thieves are able to access this information from up to 10ft away with the help of an RFID reader. Our award-winning RFIDsafe™ blocking material prevents your data from falling into the wrong hands by blocking out virtually all transmissions between 10 MHz - 3 GHz, which covers the radio frequency used in e-passports, credit cards / smart cards and key cards.
