What is a Faraday Bag?

A Faraday bag is a protective bag that blocks the transmission of electromagnetic signals. It is made of conductive materials, such as metal or a metal-coated fabric, that acts as a barrier to electromagnetic signals. This makes Faraday bags ideal for protecting sensitive electronic devices from electromagnetic interference (EMI) and electromagnetic pulse (EMP) events. As they block all incoming signals, they provide continuous data protection while preventing data leaks.

Faraday bags are commonly used to protect electronic devices, such as smartphones, laptops, and GPS devices from electromagnetic interference and location tracking. For example, if a smartphone is placed inside a Faraday phone bag, it will not be able to receive or transmit signals, including Wi-Fi, Bluetooth, and cellular signals. This makes the Faraday bag useful for preventing unauthorized access to sensitive information stored on these devices, as well as protecting the devices from malicious software that could be transmitted through the signals.

The Faraday cage, invented by Michael Faraday in the 19th Century, shields the contents from static electric fields. In layman's terms, this will block signals to and from any RFID/NFC, GPS, Wireless, WiFi, and Bluetooth signals. The faraday cage present in the faraday sleeves and faraday bags works by distributing the signals around cage so it does not penetrate. 

A more budget version of this would be to wrap your phone or your car key fob in aluminum foil, but you might get some weird looks wrapping and unwrapping your phone in foil every day. Another example is an airplane and its aluminum hull, when an airplane is struck by lightning while flying, the hull acts as a faraday cage and disperses the electricity around the hull, effectively negating the charge.

Faraday bags are commonly used in the field of forensics. Law enforcement and military agencies use our Faraday bags to prevent any tampering with electronic evidence, as well as to prevent the transmission of signals that could interfere with the analysis of the evidence. For example, if a suspect's smartphone is placed inside a Faraday bag, it will not be able to receive or transmit signals, ensuring that the evidence remains intact and untampered.

Our Faraday bags are trusted by government agencies, and they're a premier option to protect your phone, tablet, laptop, credit and debit cards, key fobs and more. All in a sleek leather or waterproof nylon, a subtle but beautiful way to secure yourself in style.
