If you plan to apply for a China Merchants Bank credit card, you can consider applying for an additional card. If your immediate family members (parents, spouse or children) have a primary card, they can apply for an additional card for you. The card type must be consistent with the primary card. When applying, you only need to simply fill in the credit card application form. The required contents include the name of the principal cardholder, date of birth, ID number and your supplementary card applicant information. Attach a copy of the supplementary card applicant's identity certificate and provide it to us. It can be processed. Log in to the credit card website, select "Credit Card Application", then select the card type you need, click "Apply for Supplementary Card", select "Customers with Card Holders", log in with the primary cardholder information, and follow the prompts to apply for an additional card.
