Repay later, with overdraft function. Therefore, types of bank cards include debit cards and credit cards, and each type of bank card has its specific uses and functions. Bank cards refer to credit payment instruments issued to the public by approved commercial banks (including postal financial institutions) with all or part of the functions of consumer credit, transfer settlement, cash deposits and withdrawals, etc. Bank cards reduce the circulation of cash and checks, allowing banking business to break through the limitations of time and space and undergo fundamental changes.
