Techion Faraday Phone and Key Signal Blocking Bags — 2-Pack RFID Blocking Pouches, Fits Phones up to 6.7" with Dual Pockets

Techion's 2 Pack RFID Signal Blocking Bags are compact Faraday pouches that block cellular, GPS and key fob signals to protect phones and car remotes from tracking and remote access. These slim, travel-ready pouches use an inner conductive lining to attenuate radio-frequency signals between 10 kHz and 3 GHz, the range used by smartphones, Bluetooth devices and most keyless car remotes. Each pack includes two dual-pocket pouches sized to fit most phones up to 6.7" and several key fobs, plus an outer storage sleeve for cards, cash or spare keys. The soft Oxford outer shell and silver-lined interior keep devices protected while remaining easy to carry in a bag, glovebox or pocket.

How does this Faraday bag stop phone tracking and wireless snooping?

The pouch's inner metallic layer forms a barrier that prevents external radio signals from reaching the device, and likewise keeps the device from transmitting out. That interruption covers common frequencies used for GPS, cellular data, Wi‑Fi, and Bluetooth, reducing the chance of remote location or unsolicited connections while the device is inside.

• Blocks signals from 10 kHz to 3 GHz to cover phone and key fob bands
• Full enclosure design prevents stray transmissions and reception
• Passive protection—no batteries or setup required

Can I use these pouches for car key remotes and do they prevent relay theft?

Yes. Placing a car key fob inside the inner silver-lined pocket stops its radio signal from being detected or amplified by thieves using relay devices. While no single product guarantees absolute prevention, isolating the fob inside a RF-blocking pouch greatly reduces exposure to remote capture attempts.

• Inner pocket sized to fit most keyless remote shapes
• Dual-pocket design separates fob from cards and cash
• Durable construction for everyday handling and storage

Will my smartphone still work for calls or navigation when it's inside?

Intentionally, no—when a phone is fully enclosed in the pouch it won’t receive calls, texts, or location updates because its antennas are isolated from networks. This is useful when you want private downtime, to avoid tracking, or to prevent apps from communicating while the device is stored.

• Designed to fully block incoming/outgoing wireless connections
• Fits phones up to 6.7" screen size (inner pocket opening 6.69")
• Use outer pocket for items that don’t require signal blocking

How portable and practical are these pouches for daily use and travel?

The Techion Faraday pouches are built for carry and convenience—compact enough for a pocket yet roomy for modern smartphones and remotes. The outer Oxford sleeve acts as a regular storage compartment, keeping essentials organized without compromising the blocking function of the inner lined pocket.

• Overall pouch size 7.7" x 4"; inner pocket 7" x 3.8"
• Lightweight materials for travel, commute, or vehicle storage
• Two-pouch pack offers spare protection for family or extra devices

Who is this for? This two-pack is for anyone who wants a simple, passive way to reduce wireless exposure for phones and key fobs: frequent travelers, privacy-conscious commuters, families sharing car keys, and people who prefer device-free moments. It’s also handy for keeping spare remotes or a backup phone secure in a purse, glovebox, or luggage compartment without adding bulk.

FAQ

Q: Do these bags block all wireless signals?

A: They block most common signals from 10 kHz to 3 GHz, covering cellular, GPS, Wi‑Fi, Bluetooth, and typical key fob frequencies.

Q: Can I leave my phone charging while it’s in the pouch?

A: No—charging or wired data transfer requires removing the device because the pouch blocks wireless and may impede cable access.
