People can exchange your ID card information for a photo of themselves, forge an ID card, and then do something inexplicable. For example, use a forged ID card to open an account in a bank, and then conduct false information fraud to let the victim remit money to this account. Once seized by the public security organ, the public security organ will find you together with the ID card, which will bring unnecessary trouble to your life.

Of course, there are many possibilities. Don't upload your identity information casually.
