Collection: Faraday Bags

Faraday Bags for Phones, Keys, Tablets & Laptops

Our signal blocking pouches and cases - also known as Faraday bags - provide physical isolation from wireless signals when correctly sealed. They can block cellular, 4G and 5G (Sub-6 GHz), Wi-Fi, Bluetooth, GPS, RFID and other radio communications, helping you control when your devices can communicate.

Leblok Security Faraday bags are manufactured in the UK using high-performance RF shielding materials. Selected models use three layers of independently tested shielding material, with shielding performance tested by the University of the Armed Forces (RF, Microwaves and RADAR Department), Germany, in accordance with recognised international standards including ASTM D-4935-10 and IEEE 299-2006.

Our range includes Faraday bags for mobile phones, car key fobs and smart keys, tablets and iPads, laptops and MacBooks, with different sizes available for different devices and everyday uses.

What Is a Faraday Bag?

A Faraday bag is a signal blocking bag or pouch that uses conductive shielding material to physically isolate a compatible device from external radio signals. When correctly sealed, the shielding material creates an enclosure around the device, preventing wireless signals from reaching it or being transmitted from it.

Faraday bags are available for different types of devices, including mobile phones, car key fobs, tablets, laptops and other compatible electronic equipment.

Unlike simply switching off a wireless function in software, a correctly sealed Faraday bag provides a physical barrier between the device and external wireless signals. This makes Faraday bags useful whenever you want a device to remain isolated until you choose to reconnect it.

Why Use a Faraday Bag?

A Faraday bag gives you a simple way to physically separate a device from wireless networks when you want it to remain isolated.

Depending on the device and situation, common uses include:

• Protecting location privacy by preventing compatible devices from communicating with mobile networks, GPS and Wi-Fi positioning systems.
  
• Reducing the risk of unwanted tracking, including situations involving personal safety, stalking or concerns about someone monitoring your location.
  
• Preventing relay attacks on car keys by blocking communication between key fobs and nearby relay equipment.
  
• Reducing unwanted wireless communication when a phone or other device is not in use.
  
• Protecting sensitive information by isolating devices during confidential meetings or other sensitive situations.
  
• Travel and border crossings, where wireless isolation can form part of a broader device-security approach.
  
• Digital detox and focused time, allowing you to put a phone away without relying solely on software settings.
  
• Reducing RF exposure from devices while stored, by preventing wireless communication when the device is correctly sealed inside the bag.
  

Faraday Bags for Different Devices

Different devices require different sizes and types of Faraday bags.

Faraday Phone Bags

Our Faraday Phone Bags are available in different sizes for mobile phones, including iPhones, Samsung Galaxy and other smartphones. The larger model also provides additional space for items such as a charging cable, passport, multiple phones, car key fobs and other small electronic devices.

Key Fob Faraday Bags

A Key Fob Faraday Bag provides a convenient way to isolate car key fobs and smart keys from wireless signals. This can help prevent keyless-entry relay attacks by blocking communication between the key and relay equipment when the key is stored inside the correctly sealed bag.

Tablet Faraday Bags

Our Tablet Faraday Bag is sized for tablet computers including iPads and similar devices. It can be useful for travel, confidential meetings, secure storage and other situations where wireless isolation is required.

Laptop Faraday Bags

The Laptop Faraday Bag provides a larger shielded enclosure for laptops and MacBooks, including larger models. It is suitable for professional use, travel, confidential environments and situations where a laptop needs to remain physically isolated from wireless communication.

Why Choose Leblok Security Faraday Bags?

Not all Faraday bags use the same construction or the same amount of shielding material.

Selected Leblok Security Faraday bags use three layers of high-performance RF shielding material, combined with reinforced stitching and a dual-fold closure designed to minimise signal leakage. The finished bags are manufactured in the UK and individually inspected before leaving the factory.

The shielding material used in these products has been independently tested by the University of the Armed Forces (RF, Microwaves and RADAR Department), Germany, in accordance with recognised international standards including ASTM D-4935-10 and IEEE 299-2006.

The relevant product pages provide detailed test results across a wide range of frequencies, allowing customers to examine the measured shielding performance rather than relying solely on general claims about the material.

What Signals Do Faraday Bags Block?

When correctly sealed, compatible Leblok Security Faraday bags can isolate devices from a range of commonly used wireless technologies, including:

• Mobile phone networks
  
• 2G, 3G and 4G
  
• 5G (Sub-6 GHz)
  
• Wi-Fi
  
• Bluetooth
  
• GPS
  
• RFID
  
• Zigbee
  
• TETRA communications
  

The exact shielding performance depends on the product, shielding material, frequency and correct sealing of the bag. For this reason, detailed test information is provided on the relevant product pages.

Choosing the Right Faraday Bag

The best Faraday bag depends on what you need to store inside it and how you intend to use it.

For a smartphone or everyday carry, a compact phone Faraday bag can be easier to carry. A larger phone bag provides more space for a phone together with accessories or other compatible items.

For a car key, a dedicated Key Fob Faraday Bag provides a compact solution for everyday storage.

Larger devices such as iPads, tablets, laptops and MacBooks require larger Faraday bags with sufficient space to allow the opening to be folded and securely fastened. The bag must always be correctly sealed for effective signal isolation.
