The black RFIDsafe TEC Slim Trifold Wallet from Pacsafe features RFIDsafe blocking material to help protect your personal data and credit card information from electronic scanning devices and identity theft. 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 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.
