Signal-blocking Faraday Box by extra digital — for phone, car keys, ID cards

Faraday Box - Signal Blocker for Phone, Car Keys, ID Cards is a compact shielding case that uses the Faraday cage principle to block electromagnetic waves. It does not emit signals and does not interfere with devices outside the enclosure. Designed for small mobile phones and other compact electronic items, the box isolates devices from incoming calls, messages and wireless connections, while protecting stored data from electromagnetic interference.

Advantages

The box blocks multiple signal types including mobile networks, Bluetooth, Wi‑Fi, GPS and RFID, and also provides shielding against static electricity and electromagnetic radiation. It serves as a protective cover for car keys, preventing remote unlocking or relay attacks, and can be used to store memory cards and other storage media to reduce the risk of data corruption or degaussing. The product is lightweight, lockable and easy to carry.

Suitable for

• Small mobile phones to temporarily block calls and messages
• Car keys to prevent unauthorized remote access and key‑fob relay attacks
• ID cards, RFID tags and access cards requiring signal isolation
• Memory cards and small storage devices to protect against electromagnetic interference
• Situations where privacy is needed and device tracking must be prevented

Key specifications

• Dimensions: 173 x 122 x 93 mm
• Weight: 360 g
• Colour: Black
• Signal blocking: RFID, Bluetooth, 4G, Wi‑Fi, GPS, GSM and similar RF signals

How to use

Open the box, place the device(s) inside ensuring they fit without forcing the lid, and close the lock. When closed, the enclosure prevents inbound and outbound wireless communications for devices stored inside. To restore normal device operation, unlock and open the box and remove the items.

Usage recommendations

Use the Faraday Box on small phones and compact electronic items only; avoid placing devices that require ventilation or continuous power while enclosed. Do not rely on the box for long‑term storage of batteries or devices that require heat dissipation. For maximum privacy and protection, ensure the lid closes fully and the lock is engaged.
