Credit cards, passports, etc. contain Radio Frequency Identification (RFID) chips that have your personal information within. This blocking material protects from ‘skimmers’ who use RFID card readers to steal your identification and information.
Within the small external zippered compartment is an RFID blocking pocket. Place your credit cards, passport, drivers license/ID, or cell phone inside this pocket to block RFID signals. This will help protect these items from ‘skimmers’ in the 10-3 thousand megahertz range of frequencies.
Please note: placing your cell phone in this pocket will block the signal and calls will go to your voicemail.
The entire backside of the pack is also lined internally with RFID blocking material. This protects you and your body against negative electromagnetic waves which come from small devices such as laptops, cell phones, tablets, etc.
