Wow! These faraday bags are of amazing quality for the price! Also, the see-through portion of the larger bag is handy for verifying that your device is no longer receiving any signal. It will fit any current smartphone. Can't wait to take this to Def Con next year!

The phone and wallet pouch were well made and durable. The window design allows you to see if your phone is doing anything it shouldn't and provides limited operation of the device without removal.

Frequently Asked Questions

How does a Faraday Bag Work?

Despite how awesome they are, Faraday bags are actually based on REALLY old tech. Specifically, the Faraday cage, so named after the English scientist Michael Faraday, who invented them in 1836.

Faraday bags are just modern versions of the Faraday cage, so they work exactly the same way.

In short, Devices like smartphones connect to phone networks via wireless signals but also have other wireless connection capabilities as Bluetooth or wireless Wi-Fi networks such as the 802.11b/g/n standard. Even with the standard security features on a smart device, they can still be susceptible to being an attack from an outside source to alter, delete or even add evidence to the phone or another device.

A Faraday bag, much like the Faraday cage, is an enclosed, sealed unit which prevents signals from being sent and received thanks to the material the bag is made from.
