If it is China Merchants Bank, you can only apply for a credit card if you are over 18 years old. You can learn more about our bank’s supplementary cards.

Applicants for supplementary cards are limited to the spouse, children, and parents of the principal cardholder. Domestic applicants must be at least 14 years old, and overseas applicants must be at least 18 years old.

The supplementary card*** enjoys the credit limit of the main card, and its accounts are merged into the main card account. Supplementary cardholders can check the supplementary card through the Palm Life App - "My" - "Check and Repayment" Card consumption details. Supplementary card points are accumulated in the name of the principal cardholder, and supplementary card repayments are credited to the principal card account.
