Temporary credit line for traffic credit card means that customers apply to the bank when necessary. After the approval of the bank, if it passes, the customer's credit limit will be increased. If it fails, the customer's credit limit will remain unchanged. Different from other banks, the method of increasing the temporary limit of traffic credit card generally requires customers to apply actively. The increase of temporary credit line of Bank of Communications is automatically judged by the credit card computer system of Bank of Communications. If the system judges that you can increase the fixed credit limit on the next credit card billing date, the customer's application for temporary credit limit increase can be approved. On the contrary, if the system judges that the fixed credit line cannot be increased on the next billing date, the application for temporary credit line increase will be rejected.

Compared with temporary increase, it is much more troublesome to improve the fixation. You can apply to the customer service of Bank of Communications for increasing the amount after using the card for 6 months, and submit the latest financial income certificate at the outlet and apply. The bank will review your credit information according to your past credit card history and repayment record, and then increase your credit card limit appropriately after the review is passed. If you want to permanently increase the quota, you must meet at least three requirements:

1, the credit record must be good: this is the most basic condition for you to withdraw money, and you must ensure that you repay in full and on time within the time when you get the card and use it. Only when the credit is good can the bank rest assured to lend you more money.

2. Spend more: This can prove that you are highly dependent on the issuing bank. If you can swipe your card, the more types of merchants, the better.

3. Consume more: The minimum standard of consumption is to use at least 30% of the existing quota every month. The greater the amount spent, the greater the possibility of raising the amount.
