Credit cards can be used to save money, but credit cards are different from debit cards. The main purpose of issuance is to stimulate consumption, not deposits and withdrawals. Therefore, although you can save money with a credit card, there is no interest.

The funds stored in the credit card account are called overpayments. This amount can increase the available limit of the credit card or be directly used for consumption repayment. If there is an overpayment on the credit card, the overpayment will be deducted first and then the credit limit. If the overpayment is greater than the consumption amount, there will be no overdraft. However, credit cards are different from debit cards. The profit payment in the credit card is not interest-bearing, and a certain amount of fees must be paid to withdraw the surplus payment.

There is a handling fee for cash withdrawals, so it can only be used for credit card consumption, which is a complete loss. The original meaning of credit card.

If you want to deposit money into a bank card, you can go to the bank's self-service repayment machine or transfer money there through online banking or third-party payment platforms.

Payment can only be used for repayment and card consumption (if there is an overpayment in the credit card account, the overpayment will be given priority when making purchases).

If you are more concerned about interest, it is recommended to apply for a debit card from Bank of China. Deposits into the debit card will earn interest. If it is bound to a credit card, it can also be used for automatic repayment. There is no point in depositing money into a credit card, and there is a handling fee for withdrawing cash.
