Faraday key wallet – signal blocker for car keys

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 affect other electrical devices outside

This car key wallet provides full protection and safety of your vehicle Secures the car against theft It also protects ID cards from information leakage
Faraday bag also works also as anti-degaussing: all kinds of memory cards and electronic products with storage media are placed in the shielding bag to prevent degaussing, protect the data information stored therein, and avoid the interference of electromagnetic fields and prevent data loss If the bank card is placed in the shielding bag, the signal of the mobile phone can be prevented from degaussing the bank card
