1. Provide sufficient proof of funds when applying. When applying for a credit card, you should provide personal financial proof as far as possible, such as income proof, bank deposit certificate, real estate certificate, car registration certificate, etc. The bank will evaluate the cardholder's assets according to these certificates. For example, if the cardholder has a deposit in CCB or is a civil servant, it will also help the cardholder to obtain good credit and also help to approve a higher credit limit;

2. Brush as many credit cards as possible. The banking industry will make a comprehensive evaluation based on customers' past use of credit cards. It is suggested that cardholders can choose several consumption modes when spending by credit card, such as household appliances consumption, catering consumption and supermarket shopping. And spend as much as possible in physical stores. The bank credit card center will adjust the amount according to the cardholder's use of credit cards and repayment records;

3. Have a good repayment record. After spending by credit card, repay on time before the repayment date of each month. Not only will you have to pay a high late fee, but you will also have a bad credit record, which will affect your application for credit cards in the future. If you can't repay on time in case of emergency, you can call the bank's customer service hotline and apply for deferred repayment;

4. Request to increase the temporary limit. Cardholders can apply at the bank to increase the temporary quota voluntarily, and the bank will comprehensively evaluate the amount that cardholders can increase according to their daily consumption and repayment. If the temporary limit is raised regularly, banks will think that the demand for credit cards is strong and it is not difficult to raise the fixed limit. Temporary quota needs to be paid in one lump sum. Please don't generate late fees.
