One main card can handle two or more bank sub-cards. Each bank credit card can only apply for two supplementary cards at most, and the main card user has the right to cancel its supplementary cards. The credit line of the secondary card can be designated by the main card user independently under the condition that it does not exceed the credit line of the corresponding main card. If the user of the primary card does not specify it, the credit limit of the secondary card is the same as that of the primary card. The above is the related content that a main card can open several sub-cards.

The difference between bank card secondary card and main card

1, the annual fee is different: the annual fee of the supplementary card is generally half of the annual fee of the main card. Most secondary cards, like the main card, can be reduced or exempted by swiping a certain number of times or amount;

2. Different lines: both the main card and the auxiliary card can be consumed, and the overdraft line of the auxiliary card is lower than that of the main card. The amount of the main card and the auxiliary card is the same. When the overdraft limit of the primary card reaches the maximum limit, the secondary card cannot be traded again.

3. Different rights and interests: the main card belongs to the account holder, has the decision-making power to change and cancel the account, and also has absolute management power over the auxiliary card. The main card holder of a bank card can apply for more than one secondary card, and can change the user of the secondary card. The secondary cardholder cannot change the secondary cardholder or the primary cardholder.
