Students can only apply for cards at local CCB outlets in Nanjing. If yes, the student ID card and ID card of Nanjing University should be provided, or one parent should be present to sign the materials about the second repayment source.
Alumni application is based on the public network, and the graduation information of State Grid can be found when CCB approves it (outlets may require graduation certificates).
On-the-job employees should provide proof of salary and income.
To sum up, there should be no cases where people who have nothing to do with Nanjing University apply for cards.
