bank cards can generally be divided into the following three categories:?

1. Debit card: what we usually call a savings card, which is a bank card that does not support overdraft function. It can be used as a current deposit to calculate and pay deposit interest. The card itself needs a balance before it can be used, and it can be used for cash withdrawal, POS consumption and transfer.

it's also very simple to open an account at a bank outlet with valid identity documents. ?

2. quasi-credit card: that is, what we usually call a credit card, which is a bank card that can be overdrawn. The overdraft amount is usually low and overdraft interest is charged in proportion every day. You can take cash, POS consumption, transfer money, etc., and the account balance also counts the deposit interest.

However, the formalities are complicated, and the person who needs to handle it and the guarantor are all employees of the enterprise owned by the whole people. The unit should refuse the credit investigation, and if it is not handled by the employees of the enterprise owned by the whole people, it should go to the bank in deposits received. ?

3. Credit card; This card is a new bank card with powerful overdraft function in recent years. There is no need to have any balance in the card. After overdraft consumption, you can enjoy interest-free periods of different lengths (up to 5 days for CCB), and you can spend overseas, support overseas foreign currency consumption, and purchase foreign exchange for repayment at home.

it's more convenient to go through the formalities than a credit card, and you don't need to find a guarantor.
