How Faraday Products Safeguard Against Electromagnetic Signals

Faraday products use metals like copper, nickel, or even silver to block electromagnetic signals from your device(s). These metals create a protective barrier around the device, stopping outside waves from messing with what is inside. This keeps your electronics safe and sound, free of unwanted inferences. 

The Difference Between a Faraday Pouch or Bag and a Faraday Cage?

It's important to note that while Faraday products share this core function of electromagnetic shielding, they vary significantly when it comes to size, shape, and intended use.

  • Faraday Pouches & Bags: These products are compact, portable, and are typically made of a material that contains metallic fibers woven into the fabric. When you place electronic devices, such as smartphones or key fobs inside these bags, the metallic fibers keep signals from entering or leaving the bag. This prevents remote access to your devices, making these bags and pouches useful for security purposes, such as preventing unauthorized scanning or hacking of RFID-enabled cards or electronic car keys.

  • Faraday Cages: These are physical enclosures made of conductive material such as copper or aluminum. When an electromagnetic field strikes the cage, the electrons in the conductive material redistribute themselves in a way that cancels out the external field's effects. This phenomenon is called electromagnetic shielding. Faraday cages are used to protect sensitive electronic equipment from external electromagnetic interference or to prevent electromagnetic signals from leaking out.
