Faraday Bag for Key Fob,RFID Key Fob Protector RF Car Signal Blocking Case Key Bag, Anti-Theft Pouch, Anti-Hacking Case Blocker，Anti-Theft Signal Blocker
RFID blocking case, each of which measures approx. 5.1 x 3.9 inches; Large enough to safely close with elastic leather to accommodate a variety of sizes of keychains and small devices, you can put a car key, several metal keys, credit card, debit card and so on at the same time
Durable material: the RFID key fob protector is made of quality carbon fiber texture material and two layers of shielding material; Shielding material provides signal blocking function, the two-layer pocket allows you to place things in different layers according to different needs to prevent confusion
Easy to use: the key fob case is practically designed to block RFID signals in the range of 10 MHz to 3 GHz, it can block the FOB signal of the car key and prevent the security system of your car from being attacked by hackers; And prevent thieves from receiving and forwarding signals from your key to prevent intrusion and keyless ignition theft
RF Blocking, EMF Radiation Protection
TOI Faraday Fabric is used for making faraday bags, EMF Radiation protection bags, Clothes, Shields, RF enclosures, EMF deflection, and signalproof rooms or tents. High-shielding nickel and copper composition blocks WiFi (2.4 & 5GHz), Bluetooth, cell signals including 5G networks, GPS, RFID, and radio signals with 90dB average attenuation from low MHz all the way up to 40GHz. EMI, RFI, and EMF radiation shielding.
EMF Emitted by Electrical Devices
EMF includes both electrical and magnetic fields emanating from electrical devices. The electromagnetic radiation is in the frequency range of 50/60 Hz (from typical power lines) through the RF range (wireless networks at 2.4 – 5.8 GHz) up to 300 GHz (microwave devices). These frequencies are all lower than visible light which is electromagnetic radiation in the frequency of 100s of THz and is much lower in energy than ionizing radiation (e.g. the type of radiation emitted by x-ray machines and radioactive materials), and the biological effects associated with exposure are much different.
FAQ
What RF signals does this fabric block?
It is 100% shielding of WiFi (2.4 & 5GHz), Bluetooth, cell signals including 5G networks, GPS, RFID, and radio signals with 80dB-100dB average attenuation. We recommend using multiple layers of the fabric for increased shielding.
