The credit card applied for is the main card. At the same time, you can apply for the supplementary card 1-2 attached to this main card. The authorization or limit of each secondary card can be set by the main card. Of course, all the consumption generated by the secondary card will also be credited to the main card account, and the main card will repay it.

Therefore: after the main card is set, some consumption types or consumption that reaches the limit will be prohibited.

At the same time, if the main card is cancelled or the arrears are frozen or reported, all rights of the secondary card will disappear together.
