1. If the secondary card of BOC series credit cards owes money, it needs to be repaid to the secondary card instead of the primary card, that is, the primary card and the secondary card need to be repaid separately.
2. The Great Wall series credit card is in arrears. Because the main card and the auxiliary card of Great Wall Credit Card are the same account, the repayment of the auxiliary card can be directly transferred to the main card or to the auxiliary card.
China Bank credit card supplementary card repayment method is as follows:
1. Active repayment: cardholders can choose China Bank Mobile Banking, China Bank Online Banking, "China Bank Credit Card" WeChat official account, colorful life APP and other channels to repay. At the same time, BOC also supports cross-bank transfer and active repayment of third-party repayment methods such as WeChat, Alipay and Lacarra. If the cardholder chooses a third party for repayment, a certain fee may be charged. Please consult the transferor for the specific amount. Since the third-party channel cannot receive the account in real time, please take the initiative to repay at least 3 working days in advance.
2. Automatic repayment: If the cardholder's primary card and secondary card have started automatic repayment business, when the secondary card owes money, it will be deducted from the designated associated repayment account, and the cardholder only needs to ensure that the repayment account is sufficient and in normal condition one day before the due repayment date.
