The Faraday Bag: Off The Grid, Not Probably Off The Grid

A Faraday bag blocks every signal your devices use, mobile, GPS, Wi-Fi, Bluetooth, RFID and NFC, so a phone, a key fob or a passport sealed inside can’t be tracked, pinged or reached. Tested shielding for everyday carry, travel, and going properly off the grid.

A Faraday bag is the difference between a guess and a measurement. You can wrap a phone in foil or drop your keys in a biscuit tin, and people do, but improvised shielding leaks. The seams, the lid, the gaps you cannot see are exactly where the signal gets through, and you never find out it failed until it matters.

If you seal a device in proper shielding, it is off the grid, not “probably off the grid”.

Either a signal can physically reach it, or it cannot.

Trust physics, not software

No setting to get wrong, no permission to audit, no update to wait for. The bag blocks the radio your devices rely on, so your privacy stops depending on whether you configured something correctly.

Built to a standard

Proper shielding is sealed, layered and tested. The best of it meets MIL-STD-188-125-2, the military standard for electromagnetic-pulse protection, and it is the same gear forensic teams use to stop a seized phone being wiped.

Why people use them
  • Off the grid on demand. A phone that genuinely stops transmitting for a meeting, a border crossing or a trip.
  • Vehicle keys. A key fob that cannot be relayed to lift the car off the driveway.
  • Cards and documents. A passport, transit card or hardware wallet, shielded from contactless reads.
  • Travel and gear. Devices carried through airports, weather or a bug-out bag, kept off the grid and dry.

Choose your Faraday bag

Every bag below is purpose-built, tested shielding, not a novelty pouch. The list runs from a single key fob guard up to a full waterproof duffel. Pick the one that fits what you carry.

Which Faraday bag is right for you?

Every bag above does the same core job: seal a device inside and the signal stops. The difference is what you carry and where you carry it. Here is the quick way to match a Faraday bag to the job.

Everyday devices

A single device you want to take off the grid on demand, or keep shielded between uses. Sleeves are the easiest, slip the device in, fold it shut, done.

Wear it every day

Shielding built into something you already carry, so the device is protected without a separate pouch to remember. Good for commuting and daily errands.

Carry your whole kit

A daily-driver backpack with a Faraday laptop sleeve built in, for the laptop and everything else you haul around. The E3 backpack adds a dedicated Faraday phone sleeve too, so it shields your laptop and phone at the same time. This is the everyday carry pick.

Weatherproof and bug-out

Signal-blocking plus waterproofing for rough conditions, travel and a kit you want ready to grab. The dry backpack is the one to bug out with; the EMP bag is for long-term off-grid storage.

What a Faraday bag will and won't do

We would rather you buy the right bag once than buy on hype. So here is the honest version, both sides of it.

What it does

While a device is sealed inside, a Faraday bag blocks the radio it uses to talk to the world: mobile, GPS, Wi-Fi, Bluetooth, RFID and NFC. No live location, no remote access, no incoming or outgoing signal.

It works the same way whether the device is on, off or dormant, which is why it stops a key fob being relayed and why forensic teams use the same gear to keep a seized phone from being wiped.

What it won't do

It is not magic and we will not pretend otherwise. Take the device out and it reconnects. A Faraday bag does not make you invisible, and it does nothing about anyone who already has your device in hand.

On contactless cards it is mostly peace of mind: modern tap-to-pay cards are protected by tokenisation, so the real value of blocking RFID is car key fobs, passports and access cards, not credit cards.

Want the science: how the shielding is tested, what the decibel numbers mean, and the real threats a Faraday bag stops? That is all in our full guide to Faraday bags in Australia.

Faraday bag FAQ

What does a Faraday bag block? +
While a device is sealed inside, a Faraday bag blocks every common wireless signal: mobile (3G, 4G, 5G), GPS, Wi-Fi, Bluetooth, RFID and NFC. The bag is a sealed enclosure of conductive fabric, so the radio those signals rely on cannot pass in or out.
Will it stop my phone being tracked? +
While it is sealed inside, yes. With no signal reaching the phone, there is no live location to report and no way to reach it remotely. The moment you take it out, it reconnects to the network, so a Faraday bag is on-demand privacy, not permanent invisibility.
Isn't foil or a biscuit tin enough? +
Improvised shielding is inconsistent. Gaps, seams and a loose lid are exactly where signal gets through, and you have no way of knowing whether it worked until it matters. A purpose-built, tested Faraday bag takes the guesswork out.
Does it protect contactless cards? +
It can block the signal, but for modern tap-to-pay cards the real-world risk is low, because each transaction is protected by tokenisation. RFID blocking matters far more for car key fobs, passports and building access cards. Buy for the threat that is real to you, not the one that sounds scary.
Does it stop key-fob relay theft? +
Yes. Relay theft works by amplifying the signal your key fob constantly broadcasts. Seal the fob in a key fob guard or any Faraday bag and there is no signal left to amplify, so the relay has nothing to work with.
Can I charge a device inside? +
No. Running a cable through the bag breaks the seal and signal leaks straight back in. If you need to keep a device charged while it is shielded, seal a power bank inside the bag with it.
Will it set off airport security? +
No. It scans as ordinary fabric and goes through the X-ray like any other bag. Plenty of travellers carry them through security without issue.
Why bag a phone that's switched off? +
A phone is never truly off while it still has power, only dormant, and a dormant phone can still report its location or wake on a signal. Sealed properly, a Faraday bag blocks the signal, so the phone has no way to report anything while it is inside.
