what are faraday bags

Faraday bags are enclosures made of conductive metallic fabric that block electromagnetic fields, such as those emitted by keyless entry systems, from reaching whatever is inside. They work as a protective shield against any incoming and outgoing radio signals, blocking all radio signals. Faraday bags are named after the inventor of the Faraday cage, Michael Faraday. They are often used to protect electronic devices from outside signals to prevent data from being altered, deleted, or added to a device. Faraday bags are used in digital forensics to prevent remote wiping and alteration of criminal digital evidence. They are also used to protect RFID devices from being skimmed. Faraday bags are an affordable, one-time investment for the protection of personal data and devices. They can be purchased for £5 or less.
