1. Concurrent processing: When applying for a credit card, check the supplementary card option when filling out the application form and provide the identity information of the supplementary card holder.

2. Follow-up processing: After the main card is issued, the main card holder can go to the bank's business outlets to fill in the application form for handling the secondary card, provide the main card number and the identity information of the secondary card holder, and submit it to the bank for processing.

Can't I do the supplementary card?

Of course. But the premise is that the main cardholder allows others to apply for supplementary cards. Usually, only the children of the main cardholder can apply for supplementary cards. In other cases, you cannot apply for a secondary card. When the main cardholder handles the credit card, he can choose to handle the supplementary card at the same time, so that he can get the supplementary card at the same time after the main card is issued.

In addition, the cardholder of the primary card has the right to decide whether to cancel the secondary card. The main card is cancelled, and the auxiliary card is also cancelled.
