Hello, 1. Credit cards are mainly used to spend first and then repay, and use the bank's funds to spend in advance and enjoy the interest-free period. This is a financial management method. 2. The credit card is not a savings card, and the interest will not be settled on the deposit in the credit card. 3. Credit cards can be used as payment tools, and can be directly consumed through the POS machines installed by merchants or online payment platforms. 4. The bank will also provide you with various forms of integral, discount, installment, lottery, promotion and other activities. 5. Credit card is the main international payment tool. On international websites, you only need to fill in your personal credit card information to shop directly. If you are on a business trip and staying in a hotel, only a credit card can complete the hotel pre-authorization for you.

Credit cards are bank cards, which can be applied through bank outlets.
