Extra Digital HB390427

Faraday sleeves for ID cards, 1 pc. The sleeves work on the Faraday cage principle, acting as a shield to block electromagnetic waves. They emit no signals of their own and do not affect other electrical devices around them. This protects the information stored on the cards from being scanned and from magnetic-field distortion caused by electromagnetic interference. For example, place bank cards inside them to protect them from being damaged when kept near a phone or other electronic devices.
