A Faraday bag is a type of Faraday cage. It protects electronics from being damaged by radio frequency interference (RFI) or from an electromagnetic pulse (EMP) by not allowing radio frequency or electromagnetic pulse waves to pass through the material.
It goes by a lot of names such as RFID bag, RFID blocking bag, or EMP bag.
How a Faraday bag works?
It creates a completely enclosed space that is surrounded by a mesh of conducting materials. When an electrical field on the outside of the Faraday cage interacts with the material, it causes the charges within the protected space to be distributed in a way that cancels the effects. It also works to protect against radio frequency interference.
This way the hackers, thieves, or government agencies who are trying to track your phone or any other device will not be able to get to it because of the outer layer of the Faraday bag.
