Faraday Bag Key Fob Signal Blocking, Faraday Cage Protector RFID Blocking, Nano Car Key fob Case Pack of 2, Waterproof, Carbon Fiber Texture,by Enjoyee
Anti-Theft Protection Modern keyless fobs carry identification chips that pick up radio signals sent out by their car. The vehicle recognises the fob when it's in range and unlocks the doors. Keyless ignition systems work in the same way - enabling cars to start when the key fob is detected in the cabin.
Criminals can exploit this via a wireless relay attack. Using a radio frequency relay booster, it's possible to pick up and then transmit a keyfob signal to trick the car into thinking a fob is present. This enables entry and theft from the cabin or boot - and, in the case of keyless ignition systems, theft of the vehicle itself.
Thanks to its 100% signal jamming capability, this faraday bag completely isolates your fob to make such attacks impossible - giving you complete peace of mind as a protector against data loss.
How does the faraday bags work? Our faraday bags makes your car safe by stopping signals being sent or received by your key fob or any other device containing data. Remove your key from the wallet and signal reception is restored immediately, enabling normal usage.
Notice: 1.Please make sure your vehicle key fob is put in to Inner layer since only the Inner layer blocks signals 2.Please make sure your electronic device is put in the silver layer, and the layer is closed completely, only that can block signal perfectly. 3.The size of these faraday bags is only designed for car key fob, not suit for mobile phones.
