Hello, if you apply for a credit card of China Merchants Bank, the most important condition is to have a stable job and income. The necessary application documents are copies of your identity certificate and work certificate. If you can provide other financial documents, it will be more helpful for us to understand your personal situation and judge the credit limit. Credit card applications are comprehensively evaluated by the system, and the specific reasons cannot be found. During this period, many factors were referred to, such as age, job stability, income, personal credit and so on. Maybe your original application materials failed to fully show your real situation, which led to the failure of your application. If your work or financial information changes in the future, you can reapply for this information after 3 months. I hope you can get a card next time!
