Whether the repayment is overdue within three days after the credit card repayment date is related to the grace period. If the grace period stipulated by the bank is less than three days or the bank has no grace period, the repayment within three days after the credit card repayment date is overdue. If the bank stipulates that the credit card repayment period is three days, it is not overdue within three days after the credit card repayment date, because the repayment within the grace period is normal repayment.

Credit card repayment is successful within three days after the repayment date, and the user's personal credit information will not be affected within the grace period.
