An overdraft card is a type of credit card. You do not need to deposit money in the card first, you can also use the card to spend or withdraw money. After spending or withdrawing money, you can return the money to the bank. Bank cards (UnionPay cards) are divided into credit cards and debit cards, and credit cards are further divided into credit cards and quasi-credit cards. Debit cards are ordinary savings cards, which are current deposit accounts and can be used for consumption, ATM deposits and withdrawals, etc.; credit cards can be used for consumption, ATM deposits and withdrawals, etc. The biggest advantage is that they can be overdrafted (with a certain credit limit). 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. Debit cards are divided into debit 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).
