What is a Faraday Bag?

It is a structure that blocks the passage of radio signals.

Why do you need the Faraday Bag?

Modern keyless fobs carry identification chips that pick up radio signals sent out by their car. The vehicle recognizes 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 key fob 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, Samfolk faraday bag can completely isolate your fob to make such attacks impossible - giving you complete peace of mind as a protector against data loss.
