Generally speaking, as long as you are a legal student or faculty member of the campus, you have the right to use your ID card and campus access card to enter the campus.

However, if a credit card is seriously overdue, it may affect your credit history and financial status, which may affect other matters on campus, such as renting a house, buying food, etc.

Therefore, it is necessary to contact the credit card issuer as soon as possible to understand the consequences and solutions of overdue repayment, and take measures to solve the overdue problem as soon as possible.
