Can a student's ID card be used to prove student identity if the school has not issued a student ID card?

No, basically major attractions use your student ID card as a voucher. The campus card does not serve as a voucher that you are currently a student.
The campus card can also prove your identity.
If you are going to a certain scenic spot or park area, you can first check if there is a relevant public account or customer service number, and call to find out first.
The campus card can prove the identity of the students. All admissions to the school must be done with real names. WeChat can also be bound. All of these can be queried.
You can ask the school official website if it can prove it.
It doesn’t seem possible. You can take it over and try it. Or go to the customer service of the official account and ask, I hope I can help you.
