RFID Antitheft Crossbody Bag

Radio-frequency communication (RFID) is widely used in credit cards, passports, and countless devices. Tech thieves can exploit these radio frequencies to compromise your credit cards simply by being in range of their signal. This bag blocks these RFID signals from entering or leaving the bag when it is closed.
This electrical phenomenon was first described in 1836 by English scientist Michael Faraday. He found that a hollow, conductive structure distributes electrostatic charges evenly across its exterior, which effectively prevents the signal from passing through. These structures are now called Faraday cages. 
This bag features several layers of metallic fabric which forms a built-in Faraday cage specifically for the most sensitive range of RFID frequencies.
