If the credit card has no limit before repayment, you cannot use the card for consumption on the day of repayment. You have to use the card for consumption after the repayment is posted the next day. If the credit card still has a limit before repayment, you can use the card to make purchases at any time within the limit.

As long as there is a balance available for overdraft in the credit card, you can overdraft the card for consumption at any time. If there is no overdraft balance in your credit card, the credit limit will be released as much as you repay, and you can continue to use the card for consumption.

The credit card statement date refers to the day when the bank settles your account, that is, the statement date.

The repayment date refers to the day before which you must repay the loan, otherwise you will have a bad record and accrue interest.
