The money owed to ICBC's deputy card needs to be repaid by the main cardholder. The consumption generated by the supplementary credit card is generally included in the bill of the main card and is repaid by the cardholder of the main card. It is precisely because the supplementary credit card is hung under the account of the main card that the supplementary credit card will be overdue, which will affect the credit information of the main card holder. Therefore, after the overdue period, the main cardholder must find ways to pay off the arrears quickly, and then take the time to patiently repair the credit information.
