The ICBC credit card supplementary card is attached to the main credit card. The functions of the main and supplementary cards are the same. You can use the same account. In fact, you can regard the main card and the supplementary card as the same card. Just put one card together. Just divided into two. First, the credit limits of the two cards are common. That is, assuming that the credit limit of your main card is 10,000, and if you spend 2,000 yuan on any card, the credit limit will only be 8,000, regardless of the main and secondary cards. Second, regardless of the consumption on the primary or secondary card, the payment will be repaid by the primary card holder. Assume that the main card has not made any purchases and the supplementary card has spent 5,000 yuan. If the repayment is not made, the bank will only pursue the claim from the main card holder. In the end, if it really affects the personal credit record, it will only be the main card holder. Someone's record has no connection with the secondary card holder.

Third, regardless of the primary and secondary cards, if the total number of purchases with both cards reaches the number specified by the bank, you can enjoy the annual fee exemption. Fourth, regardless of the primary card or the secondary card, all points earned from consumption on the two cards will be credited to the primary card. In fact, strictly speaking, there are no points for the secondary card, because the secondary card is just an extension of the primary card. Fifth, the supplementary card does not have a separate bill, and all purchases made by the supplementary card will be included in the main card bill. Sixth, the secondary card cannot exist alone. As mentioned above, the secondary card is just an extension of the main card. If the primary card is canceled, the secondary card will automatically become invalid. Seventh, the primary card holder can cancel the right to use the secondary card or change the credit limit of the secondary card at any time. In short, no matter how many secondary cards a primary card holder applies for, the secondary cards are just an extension of the primary card, and they are equivalent to the same card.

Credit card repayment: 1. Over-the-counter repayment: You can repay in cash at the counter, or by transfer;

2. ATM transfer repayment: You can pay through ATM ( outlet) will repay the loan in person. However, there is no interest-free repayment period for credit card cash withdrawals. If conditions permit, repayment should be made as early as possible to reduce interest expenses.

3. Both the primary card and the secondary card have consumption, and the limit is 5,000. If the secondary card repays 5,000, the primary card does not need to be repaid. Is that right? If the primary card and secondary card consume together, do you only need to repay it? As long as the repayment is made to the main card... Yes, the main and supplementary cards are for one account. As long as the repayment is made to the account, from the banking system, for some main and supplementary cards, the repayment is only for one account.
