Protect your identity. All US passports issued after October 2006, as well as many debit/credit cards and drivers licenses have RFID (radio frequency identification) chips that broadcast personal information 24/7. A person with a scanner could potentially read the personal data on your card or passport. The Travelon RFID blocking products blocks transmission of this information when the cards are in the RFID blocking product, compartment or pocket, preventing unauthorized access. Inside, you'll find a hidden side pocket and an easy access slide card pocket for your most used cards.
