Faraday pouch-wallet for car keys, ID cards

Faraday pouch-wallet for car keys/ID cards
Features:
The case works on the principle of a Faraday cage: like a shield, it blocks electromagnetic waves.
It does not send any signals itself and does not operate outside of other electrical devices.
Thanks to the discovery of Michael Faraday, many devices in our daily lives protect us from the effects of harmful waves or electrical discharges (such as cables, microwave ovens, cars, airplanes, etc.).
This case is designed for car keys. It blocks car key fob signals and protects the car from theft.
Due to its size, it is also suitable for ID cards, protecting them from being scanned.
A Faraday bag also protects against magnetic field distortion: it is suitable for memory cards and media to ensure information security, i.e. to prevent data loss or distortion due to electromagnetic interference (e.g., to prevent damage to a bank card by keeping it near a phone).
This key wallet also has an external key ring.
Velcro closure. Made of durable materials.
