Hello, you applied for the main card, but the auxiliary card is not mandatory. Credit card holders can apply for supplementary cards for immediate family members (parents, spouses or children), such as students who lack financial means. The secondary card and the primary card share the credit line, and the account will appear on the same statement. In addition, the rights and obligations of the main card and the auxiliary card are basically the same.

If you have any other questions, please open www.cmbchina.com, the homepage of China Merchants Bank, and click "Online Customer Service" in the upper right corner to enter the consultation.
