The conclusion is that upgrading CITIC Bank's credit card to Platinum Card is indeed possible to increase the credit limit. The specific situation depends on the cardholder's card use and contribution. If the credit card record is good, there is no overdue, and there are appropriate consumption contributions, such as installment payment and cash advance, you will usually see an increase in the quota after upgrading. The initial amount of the Platinum Card of CITIC Bank is at least 5, yuan. In contrast, the amount of the Puka Card and the Gold Card ranges from 3, to 1, and from 1, to 5,. Effective strategies to increase the quota include spending in high-end merchants, maintaining the quota utilization rate of about 3%, paying in full on each billing day, and maintaining good repayment habits. At the same time, protecting credit card information, avoiding excessive and frequent use, and rational use of interest-free period for financial management are all important factors for raising the amount. The above information comes from the official information of CITIC Bank Credit Card and VISA Platinum Card.
