1. Debit card: Debit cards are divided into two types, one is a savings card, which is mainly used for deposit; The other is a wealth management card, which can directly handle the related business of bank wealth management;

2. Credit card: There are two kinds. One is a credit card, which is a narrow credit card. With a credit card, you can spend first and then repay, but the deposit has no interest; The other is quasi-credit card, which has some functions of credit card and debit card. The deposit has interest and can be used for small overdraft consumption, but its consumption limit is not as high as that of credit card, and the arrears must be paid off in one lump sum.
