Extra Digital HB390410

Extra Digital HB390410

A Faraday case/wallet for car keys and ID cards. The case works on the principle of a Faraday cage: it acts as a shield that blocks electromagnetic waves. It does not emit any signals itself and does not affect other electrical devices outside it. Thanks to Michael Faraday's discovery, many everyday devices protect us from harmful waves or electrical discharge (such as cables, microwave ovens, cars and aircraft). This case is designed for car keys: it blocks the signals from car key fobs, protecting the vehicle against theft. Its size also makes it suitable for ID cards, protecting them from being scanned. The Faraday pouch also guards against magnetic field distortion, making it suitable for memory cards and storage media to keep information safe and avoid data loss or corruption from electromagnetic interference (for example, to avoid damaging a bank card kept near a phone). This key wallet also has an external key fob holder.
