Faraday bags provide essential radio frequency (RF) shielding for electronic devices. To ensure maximum privacy protection, follow these steps:
Selecting & Verifying Your Bag
- Choose certified bags: Prioritize bags explicitly tested and certified against standards like MIL-STD-188-125 or equivalent, blocking RF signals effectively.
- Check sizing: The bag must be large enough to fully enclose the device without excessive empty space, yet avoid overcrowding.
- Pre-use Test is mandatory: Insert a powered-on device (phone, tracker). Seal the bag. Move away. Verify complete loss of signal (calls, data, GPS, Bluetooth, Wi-Fi). Never assume a new bag works without testing.
Correct Usage Procedure
- Power off devices (Recommended): While the bag blocks signals, powering down adds a security layer against potential malware waking the device.
- Place device inside: Ensure no cables, accessories, or metal objects accidentally connect to the device inside.
- Fold the opening meticulously: Overfold the open end at least three times. Pay close attention to the corners.
- Secure the closure: Firmly press the Velcro or sealing strip along the entire folded length until it fully adheres. Ensure a completely flat, tight seal.
- Isolate bagged devices: Keep the sealed bag physically distant from other electronic devices or metallic surfaces.
Maintenance & Limitations
- Regularly re-test: Conduct the signal block test periodically (e.g., monthly) and after any potential damage.
- Handle with care: Avoid sharp objects, punctures, excessive bending, or abrasion which damage the conductive liner.
- Protect the seal: Keep the closing mechanism clean. Replace bags if the seal weakens.
- Store properly: Keep in a cool, dry place away from direct heat or humidity to preserve shielding integrity.
- Understand the limit: Faraday bags block wireless signals only. Physical access to the device (if retrieved) or stored data remains a separate vulnerability.
Critical Reminder: Proper folding and sealing are paramount. A bag stored "unfolded" or with a poorly sealed corner offers minimal or no protection. Always test.
