The quasi-credit card appeared earlier than the credit card and can be said to be a trial version of the credit card. Since the two cards belong to different accounts and have different management departments, the credit card is managed by the credit card center, and the quasi-credit card is managed by the credit card center. The cards are managed by the Debit Card Center. Generally speaking, the limits cannot be combined. The limits of the two cards can be used separately without affecting each other (but if one card has bad credit, both cards may have their limits reduced or even be deactivated)
