Universal Signal-Blocking Pouch — Phone & Car Key Faraday Case

Universal Signal-Blocking Pouch

A versatile Faraday pouch that blocks common wireless signals around whatever you seal inside — a phone, car key fob, or cards. Use it to stop relay attacks on keyless-entry cars, cut phone tracking and notifications on demand, or shield contactless cards.

What it does

• Blocks common wireless signals — cellular, Wi-Fi, GPS, NFC/RFID, and keyless-entry RF — when a device is fully sealed inside
• Stops relay amplification of car key fob signals to help prevent keyless-entry theft
• Works as an RFID sleeve for contactless cards
• Fold-over closure seals in seconds; opens just as fast when you need signal back

Construction

• Inner silver shielding layer, 680D waterproof Oxford outer
• Size: 20 × 10 cm (fits most phones) · carry loop included
• Available in several colors

To verify: seal a phone inside and call it — no ring means it's working.
