Signal Killer Faraday Bag

Faraday bags are a simple and convenient way to protect electronic devices from interference.

They’re named after Michael Faraday, an English scientist who made a number of breakthroughs in the field of electromagnetism.

Most Faraday bags use copper mesh to protect from radio frequencies and electromagentic signals. It’s like a physical Airplane Mode for your phone or any other device within the bag.

You can use a Faraday bag to protect any electronic or Internet-connected device. A Faraday bag will block your phone’s GPS signal, your credit card’s NFC chip, and the Bluetooth signal to and from your Bluetooth enabled crypto hardware wallet. 

Signal Killer Faraday bags are produced by Privacy Pros, the same company behind the Billfodl.

Signal Killers come in two sizes: large and small.

This material blocks WiFi (2.4 & 5GHz), Bluetooth, cell signals (4G LTE+), GPS, RFID, and radio signals with an average of 60-80dB attenuation.

The Signal Killer has two velcro strips that run the entire width of the bag. To seal the bag and effectively block out all signal, you simply roll the top of the bag down and fasten it with the velcro.
