According to the inquiry of China Construction Bank official website, we know that there is no dedicated APP for CCB credit cards, and only one CCB APP has been developed, which can manage both bank cards and credit cards. It can be downloaded and used in major mobile phone application markets. The services provided by China Construction Bank APP include credit card service, investment and wealth management, loan and life service. If you are a credit card customer of China Construction Bank, you can log in to the APP to check your credit card bill and card, and you can also make credit card repayment. In addition, you can also handle various credit card installments, such as bill installment, consumption installment and cash installment. Of course, customers who do not have a CCB credit card can also apply for a credit card through the APP.
