The relationship between the credit card sub-card applicant and the main card applicant must not be siblings, because the sub-card applicant must be the immediate family members of the main card applicant, that is, parents, children or spouses, and the applicant must be 14 years old. The card type of the supplementary card is the same as that of the main card, and there is no independent account, so you can't log in to the online bank belonging to this card alone, and you won't keep accounts separately. The repayment will be directly transferred to the main card account, sharing the credit line with the main card.
