Hello, if you use the savings card of China Merchants Bank and you have a fixed income every month, it will help you apply for a credit card successfully. Generally speaking, the bank will pay attention to the cardholder's work certificate and income certificate when approving, so the monthly flow of your bank card is relatively stable, so the bank will have more confidence in your repayment ability. Therefore, bring a copy of your ID card and other property certificates to China Merchants Bank to apply. Generally, there is no problem, but the amount depends on the materials you submit!
