Muu HB390441

Other HB390441

A Faraday wallet case for a car key and ID cards. The case works on the Faraday cage principle, acting as a shield to block 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. This case is designed for car keys: it blocks the signals from car key fobs, protecting the vehicle from theft. Its size also suits 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 data safe, avoiding loss or corruption caused by electromagnetic interference (for example, to avoid damaging a bank card kept near a phone). This key wallet has two key rings, one inside and one outside, with a clip for an RFID fob.
