After authentication is completed, there will be an electronic signature step. For example, when using the "Registration Authentication" APP for real-name authentication, after the real-name authentication is passed, it will enter the electronic signature link. At this stage, you need to confirm and sign the relevant information, and then click OK to complete the to-do list.

Different places and different businesses will be different, so it is best to refer to the specific regulations of the region or consult relevant departments.
