The reason why I have two credit cards is that the other one should be an additional card. It is possible that I checked the option to apply for an additional card when applying for a credit card. Supplementary cards are relative to the main card. Each principal cardholder who opens a credit card can apply for additional cards for other natural persons with full civil capacity, such as spouses, children, and parents (applicants for additional cards who are under 18 years old must obtain the consent of their legal representatives). Domestic applicants must be at least 14 years old, and overseas applicants must be at least 18 years old. If the applicant does not want to have an additional card, he can call the bank staff and ask to cancel the additional card.

The supplementary card*** enjoys the credit limit of the main card, and its account is merged with the main card account and does not issue separate bills. Supplementary card points are accumulated in the name of the principal cardholder, and supplementary card repayments are credited to the principal card account.

Special reminder:

1. Generally, each main credit card can only apply for two supplementary cards at most. Some banks will stipulate independently, and the specific regulations are mainly based on the bank's regulations.

2. The credit limit of the supplementary card does not exceed the credit limit of the main card. The specific limit can be designated by the main card holder. If not specified, it will be the same as the main card limit.

3. The main cardholder has the right to cancel the supplementary card.
