Shenzhou Mingda mobile phone shield bag uses advanced special metal barrier materials, which can effectively shield the signal of the full-system (2G\3G\4G\5G) public mobile communication terminals to prevent information leakage caused by the use of mobile phones.

Prevent mobile phone information leakage: Putting the mobile phone into the shielding layer can shield the mobile phone signal, prevent the mobile phone from being illegally tracked and located, prevent the mobile phone information from being illegally stolen, and prevent the use of mobile phones to eavesdrop on the voice of private places through the public mobile communication channel.

Mobile phone electromagnetic radiation protection: Put the mobile phone into the outer layer to reduce the electromagnetic radiation of the mobile phone while maintaining normal communication.

Prevent bank cards and credit cards from demagnetization: All kinds of memory cards and electronic products with storage media are placed in the information security bag, which can protect the data information stored in it, eliminate static electricity, reduce the interference effect of electromagnetic fields on the storage content, and prevent data loss.
