When to Use a Faraday Bag
High-Risk Situations:
- ✊ Protests or demonstrations — Prevent location tracking and identification
- ✈️ Border crossings — Prevent remote hacking or forced searches
- 🤝 Confidential meetings — Ensure phones can't be remotely activated as listening devices
- 🏠 Escaping domestic violence — Prevent abuser from tracking your location
- 🚗 High-risk travel — Moving through dangerous areas
- 🎯 Under active surveillance — When you know you're being tracked
Everyday Privacy:
- 🏡 At home — When you want complete digital disconnection
- 💼 Storing devices — Keep spare phones/tablets untraceable
- 🔋 Preserving battery — Phones in Faraday bags don't drain searching for signal
How to Test Your Faraday Bag
- Call your phone — Place it in the bag, seal it, then call from another phone. It should go straight to voicemail.
- Check Find My — Open Find My app on another device. Your phone should show as "Offline" or "No location found"
- Try WiFi — Before sealing, turn on WiFi. After sealing, try to ping the device. It should be unreachable.
- Bluetooth test — Try to pair with a Bluetooth device. Connection should fail.
- GPS test — Use a GPS tracking app. Location should freeze when bagged.
⚠️ Important: Proper Sealing
Faraday bags only work when properly sealed. Even a small gap can allow signals through. Always:
- ✅ Fold the top 3 times (for roll-top bags)
- ✅ Ensure velcro is fully closed
- ✅ Check zippers are completely sealed
- ✅ Don't let metal (keys, coins) touch the fabric
- ✅ Test regularly to ensure effectiveness
What Faraday Bags DON'T Protect Against
- ❌ Physical access — Someone can still take your phone out of the bag
- ❌ Data already on device — Doesn't encrypt or delete data
- ❌ Malware — Doesn't remove spyware or viruses
- ❌ Past tracking — Only prevents tracking while bagged
💡 Combine with Other Protections
For maximum security, use Faraday bags alongside:
- 🔐 Strong passcode — Protect if bag is opened
- 🔒 Full disk encryption — Enabled by default on iPhone
- ❌ Disable biometrics — Before high-risk situations
- ☁️ Turn off iCloud — Prevent remote access
- ✈️ Airplane mode — Extra layer before bagging
Legal Considerations
Faraday bags are legal in most countries, but:
- ⚖️ Legal to own and use — Not illegal in US, EU, most countries
- 🚔 May raise suspicion — Law enforcement may question why you have one
- ✈️ TSA/Airport security — May inspect the bag but it's legal to carry
- 🏛️ Court orders — Can't be used to obstruct justice or ignore court orders
