If your savings card and credit card are bound to an agreed repayment account, as long as there is enough money in the savings card, you don't have to repay it yourself, and the bank will deduct the money.

The bank will deduct money from your savings card the day after the last repayment date of your credit card every month, but don't worry, it is timely repayment. Don't be nervous if the amount in your savings card is insufficient and the deduction is unsuccessful. You can directly deposit the money into your credit card after the final repayment date, or deposit the money into your savings card before the fourth day after the final repayment date, and deduct the money from the bank on the fifth day after the final repayment date, which is considered as timely repayment.
