Debit cards are divided into two types: savings cards, which are issued by banks for general customers, and bank cards, which are often called such cards, are mainly used for deposits.

Financial cards are issued by banks for high-end customers, and can directly handle the related business of bank wealth management.

There are also two kinds of credit cards, namely: credit cards, which is what we often call narrow credit cards. With it, you can spend it first and then pay it back, but there is no interest on the deposit.

Quasi-credit card, which has some functions of credit card and debit card, can make small overdraft consumption with deposit interest, but its consumption limit is not as high as that of credit card, and the arrears must be paid off in one lump sum. Few people use this card.
