Understanding Faraday Bags

What is a Faraday bag?

A Faraday bag is a portable enclosure made of a form of conductive material, such as copper or aluminium, that blocks electromagnetic signals, including those from cell phones, Wi-Fi, Bluetooth, and GPS. By creating a Faraday cage, these bags prevent all signals going in or out, protecting them from hacking, tracking, electromagnetic interference & the owner from constant distraction. They are widely used for privacy, security, and digital forensics and are available in various sizes to accommodate devices such as phones, laptops, and car keys.

How does a Faraday bag work?

Faraday bags operate on the principle of a Faraday cage, which redistributes external electromagnetic charges across its conductive surface, cancelling out the field inside. Made with layers of metalised fabric or mesh, these bags block radio frequency (RF) signals, ensuring devices inside cannot send or receive data. This isolation protects against remote access, tracking, and EMPs, making Faraday bags a reliable tool for securing sensitive electronics. Not all Faraday bags are made equal, though; ensure you buy the best when it comes to protecting what you value. Not only is SCRTnz Faraday fabric 'EliteBlock' tested and certified to the highest standard, but we use triple layers in all of our products to offer the highest protection in the world to whoever you are.
