Is it safe to upload your ID card online?

According to the relevant national laws and policies, users need to upload the scanned information of their ID cards to purchase telecom products through electronic channels, so as to compare them with the data of the Ministry of Public Security. When purchasing Unicom communication products, the photo of the certificate you uploaded is only used for registration in the real-name registration system. And after all your photos are uploaded, the system will automatically print the words "China Unicom is only used for network access" and the date, and it is only used for this network access business. There is no danger of leakage.
