Faraday Bag for Key Fob (2 Pack), Faraday Cage Protector - Car RFID Signal Blocking, Anti-Theft Pouch, Anti-Hacking Case Blocker
Faraday bag provides a complete signal blocker for your vehicle key fob. This prevents thieves from picking up and relaying signals from your key, to shield against break-ins and keyless ignition theft
Faraday bag is constructed with premium carbon fiber textured material and two-layers of shielding materials packed in a gift box. It provides signal blocking functions as well as a luxurious fashionable appurtenance
The smaller/front pocket is anti-radiation, best for storing ID card, bank cards, etc. The larger/back pocket is for signal blocking, best for storing car key fobs
Dimensions: 3.5" x 5.0". Secure closable flap with elastic accommodates multiple sizes of keychains and small devices. The integrated keychain hole provides more flexibility
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 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.
