I bought these to carry items through the airport. As long as the tops are folded under twice, they worked really well for both my cell phone and car fob.

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.

There are many reasons you might want to use a Faraday bag

- Avoids the problem of the mobile phone or device becoming PUK locked.

- The Large bag included in this bundle has a window that allows the user to preview the screen of your electronic devices without having to take it out of the bag, allowing you to be secure in the knowledge that the device is not being remotely accessed while in use.
