Hello, what is the reason why the campus card of Guangdong University of Finance and Economics can't enter the library? The reason why the campus card of Guangdong University of Finance and Economics cannot enter the library is that it has been cancelled. In Guangdong University of Finance and Economics, the campus card was cancelled after graduation, and it was impossible to enter the school gate and the library. Although the official website says that the campus card can be used as an alumni card after graduation, it can enter the entrance guard, but it is not actually done! The graduate information will be deleted by the system, and the campus card will become a waste card.
