Faraday Bags & Protection

What is a Faraday bag?

A Faraday bag (also called a signal-blocking bag or Faraday pouch) is a specialised enclosure made with conductive fabric that creates complete digital isolation. Once your phone, tablet, laptop or key fob is sealed inside, it can no longer send or receive cellular, Wi-Fi, Bluetooth, GPS or RFID signals. SCRT Faraday bags use triple-layer EliteBlock™ fabric for forensic-level protection, trusted by professionals who need reliable signal blackout.

Why not just turn my phone off?

Modern smartphones are never fully powered down. Even in “off” mode they can still maintain limited connectivity, collect data, or be remotely activated. Placing the device in a Faraday bag is the only reliable way to guarantee complete signal isolation.

Do Faraday bags provide EMF protection?

Yes. SCRT Faraday bags are lined with triple-layer EliteBlock™ shielding fabric that blocks a wide range of electromagnetic fields (EMF and RF radiation). When your device is sealed inside, exposure to cellular, Wi-Fi and Bluetooth radiation is dramatically reduced.

Will I see my missed calls and texts when I take my phone out of the Faraday bag?

Yes. As soon as you remove the device and it reconnects to the network, it will receive all pending texts, emails, voicemails and notifications.

Will my alarm still go off if my phone is inside a Faraday bag?

Yes. Alarms and timers that rely on the phone’s internal clock continue to work normally because they do not require any wireless signal.

How do I know the Faraday bag is working?

The quickest way to test any Faraday bag is to place your phone inside, seal it fully, and try calling the number. If the call goes straight to voicemail and the phone shows no signal bars, the bag is working correctly. This simple test confirms the signal-blocking performance of our EliteBlock™ fabric.

Are the Faraday bags waterproof?

Many of our bags (including the waterproof phone bags and dry bags) are fully waterproof. Check the individual product description for specific water-resistance ratings.

Do your products block RFID and contactless payments?

Yes. All SCRT Faraday products block RFID, NFC and contactless signals, protecting passports, credit cards and access cards from skimming.

Can I use a Faraday bag for car key fobs?

Yes. Faraday key fob bags are one of the most effective ways to stop relay attacks. Simply place your car key or keyless entry fob inside a SCRT Faraday key fob bag or the Digital Detox & Key Fob Box and the signal is completely blocked, preventing thieves from amplifying it.

What is the difference between single-layer and triple-layer products?

Single-layer offers good everyday protection. Triple-layer EliteBlock™ fabric delivers significantly higher attenuation and is used in all our premium Faraday bags and sleeves for forensic-level performance.

How long does the Faraday protection last?

The conductive fabric retains its shielding properties indefinitely under normal use. Avoid sharp objects, excessive folding of the conductive layer, and harsh chemicals to maintain maximum performance.

EMF-Blocking Clothing

Does SCRT clothing block 5G?

Yes. Our EMF-blocking clothing is made with laboratory-tested shielding fabric that provides strong attenuation from 10 MHz to 6 GHz+. This range covers current 5G mid-band frequencies used in New Zealand and Australia (including the 700 MHz band). Higher millimetre-wave 5G frequencies (above 20 GHz) have not been extensively tested.

Is SCRT clothing effective?

Yes. Independent laboratory testing shows our EMF-blocking fabric delivers between 35 dB and 80 dB of attenuation across the tested frequency range. This means only a very small percentage of radiation passes through the material. The clothing offers targeted protection for the head, neck and torso rather than full-body coverage.

Why is my phone still ringing when it’s under the SCRT cap?

Signal-blocking apparel works by reducing signal strength, not by creating a perfect seal like a fully enclosed Faraday bag. If the ambient signal is extremely strong, a small amount may still reach the phone. The cap still greatly reduces the radiation reaching your head.

Can I measure the EMF blocking effect with my cell phone?

No. Phone signal bars are not accurate measuring tools. Different phones react differently, and signal strength fluctuates constantly. The only reliable way to measure attenuation is with professional RF test equipment. Our fabric has been independently tested in laboratory conditions.

Can I wash the EMF-blocking clothing?

Yes. Most items can be gently hand-washed or machine-washed on a cold, delicate cycle. Avoid bleach, fabric softener and high heat. Always check the care label on the product.
