Debit cards are divided into transfer cards, special cards and stored-value cards according to different functions. Debit cards cannot be overdrawn. Debit cards have the functions of transferring money, depositing and withdrawing cash, and spending money. A special card is a debit card used in a specific area and for special purposes (referring to purposes other than department stores, restaurants, and entertainment industries). It has the functions of transferring funds, depositing and withdrawing cash. A stored-value card is a prepaid wallet-style debit card in which the bank transfers funds to the card for storage at the request of the cardholder and directly deducts funds from the card during transactions.

Debit card (debit card) can be used for consumption online or at POS, or transfer and withdrawal through ATM. Overdraft is not allowed, and interest is calculated on the amount in the card based on current deposits. Funds are withdrawn directly from the savings account when spending or withdrawing money. Debit cards generally require a password (PIN) when used. Debit cards can be divided into ordinary cards, gold cards and platinum cards according to their levels; they can be divided into domestic cards and international cards according to their scope of use.

Credit cards are divided into credit cards and quasi-credit cards. A credit card refers to a credit card in which the card-issuing bank gives the cardholder a certain credit limit, and the cardholder can consume within the credit limit first and repay later. A quasi-credit card refers to a credit card in which the cardholder first deposits a certain amount of reserve fund as required by the bank. When the reserve fund is insufficient to pay, the cardholder can overdraw within the credit limit specified by the card-issuing bank.

The quasi-credit card is a single-currency, single-account credit card that bears interest on deposits and is settled in RMB when swiping the card. It has functions such as transfer settlement, cash deposits and withdrawals, credit consumption, and online banking transactions. When the account balance is insufficient for payment by swiping the card for consumption or cash withdrawal, the cardholder can overdraft consumption or cash withdrawal within the prescribed limited credit limit, and a certain amount of interest will be charged. There is no interest-free repayment period.

Quasi credit card is a type of credit card with Chinese characteristics. There is no such type of credit card abroad. In the late 1980s, China's banking industry introduced credit card products from abroad. Because China's personal credit system was not very complete at that time, the Chinese banking industry made certain changes to foreign credit card products. The traditional foreign credit card credit card deposits had no interest and overdrafts had an interest-free period. Instead, deposits had interest and overdrafts were not interest-free.

A quasi-credit card has some functions of both a credit card and a debit card. It generally requires a deposit or a guarantor. When using it, you deposit first and then consume, and interest is calculated on the deposit. Cardholders can make small overdrafts within the limit approved by the card issuer when making purchases, but interest will be calculated on the overdraft amount from the date of overdraft, and the balance must be paid off in one go. There is no interest-free repayment period and minimum repayment amount. The basic functions are transfer settlement and shopping consumption.
