The supplementary credit card will be included in the bill of the main card after the payment is made, but the supplementary card allows you to pay off the debt of the supplementary card separately. As for the main card, you can pay back the total bill amount of the main card and the supplementary card. However, most of the time, after a credit card payment is made, the main card will be repaid uniformly, and the secondary card does not need to be repaid separately.
