We all know that credit cards, as a tool for overdue consumption, are very popular and have attracted the attention of countless consumers. Generally, credit cards distinguish between primary cards and supplementary cards, so some netizens asked, how to apply for a supplementary credit card? Let’s find out together.

Credit Card It is understood that there are two main ways to apply for a supplementary credit card, one is to apply for it at the same time as the main card, and the other is to apply for it after the main card is issued. For example, after the main card is issued, the main cardholder needs to go to a bank branch to fill in the application form for the supplementary card, provide the main card number, and the supplementary cardholder's identity information and then submit it to the bank.

Moreover, the credit limit of the supplementary card and the main card are exclusive. If the credit limit of the main card is increased, the limit of the supplementary card will also be increased. Although the main card and the supplementary card have the same limit, if the main card's consumption reaches the credit card limit, the supplementary card cannot make purchases.
