1. General credit cards can only be handled by the applicant's salary certificate, and college students' cards can be handled by personal credit. Although a student ID card is required, there is no property guarantee.

2. The credit card limit of college students is often not very high. The maximum credit card limit of domestic banks is 3,000 yuan for undergraduates, 5,000 yuan for postgraduates and 8,000 yuan for doctoral students. When you use a credit card, you need to repay it on time. Don't delay repayment, or you will have a bad credit record.
