Common Questions
Frequently Asked
What signals do these Faraday bags block?
Mission Darkness bags block all wireless signals including WiFi (2.4/5GHz), Bluetooth, cellular (5G/LTE/4G/3G), GPS, RFID, and NFC. The TitanRF™ fabric provides 80+ dB of attenuation from low MHz through 40GHz.
What's the difference between window and non-window bags?
Window bags have a transparent RF-shielded panel that lets you see the device screen without opening the bag — useful for confirming signal block, checking battery level, or monitoring device state. Non-window bags are fully opaque for maximum concealment.
What is NeoLok closure?
NeoLok is a magnetic closure system that allows rapid one-handed deployment. The magnets create a strong seal while remaining easy to open and close quickly — ideal for law enforcement and field forensics where speed matters.
Will the bag fit my phone?
Yes. Phone-size Faraday bags are designed to fit all modern smartphones including the largest models with cases. For exact interior dimensions, check the individual product page.
How do the Charge & Shield bags work?
Charge & Shield bags include a filtered power pass-through that lets you charge a device inside the bag without compromising RF isolation. The power cable is shielded, so no signal can escape through the charging port.
Are these bags used by law enforcement?
Yes. Mission Darkness bags are used by federal agencies (FBI, DEA, Secret Service, DHS), military branches, and police departments worldwide for digital evidence seizure and chain-of-custody preservation.
How do I know the bag is actually blocking signals?
Place your phone inside the bag and seal it completely. Then try calling or texting the phone from another device — the call should go directly to voicemail. You can also check that WiFi, Bluetooth, and GPS are unreachable. Window bags let you visually confirm the signal indicators drop to zero.
How long do Faraday bags last?
Mission Darkness bags are built for professional daily use. The TitanRF™ fabric is durable and does not degrade with normal handling. Avoid puncturing or tearing the shielding material. With proper care, these bags will maintain their shielding performance for years.
Can I use my phone while it's inside the bag?
No — that's the point. When sealed, the bag blocks all incoming and outgoing signals. If you need to interact with a device while it's RF-isolated, consider the BlockBox Lab or a Faraday tent with built-in conductive gloves.
What's the difference between a Faraday bag and airplane mode?
Airplane mode is a software setting that can be overridden remotely or by malware. A Faraday bag provides physical, hardware-level RF isolation that cannot be bypassed by any software. For chain-of-custody forensics and true signal blocking, only a Faraday enclosure provides guaranteed protection.
Do keyfob bags prevent relay attacks on my car?
Yes. Relay attacks work by amplifying the signal from your keyfob to trick your car into unlocking. Placing the keyfob inside a Faraday bag completely blocks that signal, making relay attacks impossible. It's one of the simplest and most effective countermeasures available.
Do you offer bulk or government pricing?
Yes. We offer volume discounts for agencies, departments, and organizations. Mission Darkness products are available on GSA Schedule and through authorized government procurement channels. Contact us or request a quote for custom pricing.
