Hello, if the two cards are opened with the same ID, the bills will be calculated together. When repaying, you can pay it to any card.

The card issuer's repayment to the cardholder will be in the order of bills issued and bills not issued, and the portion of bills issued will be based on the annual fee, interest, fees, cash advance or transfer transaction cost. Pay off their arrears one by one in the order of deposit and consumption transaction principal.
