After handling the student credit card (debit card), there is no limit in the card. If you want to use it, you need to save money before spending it. In this way, students can accumulate good credit records during this period, which is helpful to apply for mortgage and credit card (debit card) after graduation. If parents are willing to provide repayment guarantee to the bank, the bank will give students a certain amount of credit card (debit card), and then the student credit card (debit card) can overdraw.
In short, students' credit cards (debit cards) can only be used normally if they are deposited in the cards before graduation.
