Supplementary cards cannot apply for withdrawal, but they can use their credit lines together with supplementary cards. In addition, the usage habits of the secondary card will also affect the withdrawal amount of the main card to a certain extent. Of course, if the secondary card is used properly, it will naturally contribute to the withdrawal amount of the main card, so the amount will increase.

How to use the secondary card to increase the limit of the main card?

As far as withdrawal is concerned, the following must be done:

1, swipe your card more than 5 times a month, preferably 10 times or more, preferably 20 times or more.

You can't pay until you pay, which is the best performance of your ability to pay.

3. After paying off the debt, it is best to brush it the next day or the third day, and it is most taboo to brush it when it is returned on the same day.

4. Banks like cardholders to apply for bank debit cards, and it is recommended to use credit cards to bind bank debit cards for self-repayment. Not only is it conducive to raising your own quota, for example, Bank of Communications attaches great importance to this point, and good loans will find such customers.

There is no need for a minimum repayment amount, which is also a scoring standard that affects repayment ability. Although the bank also supports your minimum loan repayment, don't do it all year round. It is suggested that according to your financial situation, it is best to repay in full and in appropriate installments to avoid the minimum repayment amount.
