1. If the balance of your Tenpay account is enough to pay the credit card repayment, you can choose to directly use the balance of TenPay to repay.
2. If the balance of your Tenpay account is insufficient, or you choose to pay by savings card (online banking payment), you will not use the money in Tenpay, but pay through the channel of Tenpay. It is equivalent to recharging Tenpay with your savings card online banking, and then returning the credit card.
