The black RFIDsafe TEC Passport Wallet from Pacsafe has a passport-holding compartment and four easy access card slots in a lightweight, heat-welded design with a soft microfiber lining. Most passports, credit cards, and ID cards have an RFID micro-chip that contains personal and sensitive information. This information can be accessed from up to 10 feet away with the help of an RFID reader. The RFIDsafe blocking material prevents your data from falling into the wrong hands by blocking out virtually all transmissions between 10 MHz to 3 GHz. It covers the radio frequency used in e-passports, credit cards / smart cards, and key cards.
