1. when filling in the application form, there are several small details that affect the credit line, such as whether there is a fixed telephone number in this city, whether this number is registered in your own name or the name of your family, whether you are married, whether your mobile phone number has a monthly rent, and whether it is a local account. If the above answers are in the affirmative, the bank will greatly increase the credit evaluation, but each condition is not absolute, but it is relatively easy to pass the qualification examination and improve the initial application for consumption limit. Consumer credit and repayment credit are still the most valued by the bank.

2. Don't forget to swipe your card anytime and anywhere. During the period of using the card, you should spend more by swiping the card. You should try to choose a store with swiping the card for food, clothing, housing and transportation. The more frequently you use it, you will have a relatively stable spending quota every month, just changing the original habit of cash consumption to swiping the card. This shows the loyalty to the bank. The bank's information system will count the frequency and amount of credit card swiping, and the credit limit will be automatically raised in about half a year.

3. Repay on time and maintain good credit. If you owe money, you can borrow it if you change it. Banks also strictly follow this ancient truth. If you don't change the money on time, you will definitely have no credit. You'd better pay it back in full, not just the minimum repayment amount. Cycling interest will make you unbearable.

4. Take the initiative to apply for increasing the credit limit. After normal use of the credit card for half a year, you can take the initiative to submit a written application or adjust the credit line through service electricity, and the bank needs approval. Under normal circumstances, the credit line will be increased to a certain extent after reviewing the consumption records and credit records.
