The so-called credit card limit increase is actually a method of increasing the limit by relying on the credit card limit. But in fact, increasing the credit limit with an empty card is not 100% effective. If you want to succeed, you must pay attention to the following points:

The operation of increasing the credit card with an empty card cannot empty the credit card limit in one go. It should be increased to more than 90 After that, go and buy goods with a value between 10 and the remaining balance = 20. When a successful transaction indicates that a credit card over-limit has been triggered, the corresponding credit card limit will also be increased.

And it cannot be ruled out that some banks do not have over-limit services, which may cause credit card transactions to fail. In this case, the cardholder can proactively call the customer service hotline of the card issuer and indicate that he does not have enough credit to request a withdrawal. But in this case, even if the bank gives you a withdrawal limit, it is likely to be a temporary limit.

At the end, I would like to remind you that empty credit card withdrawals involve over-limit fees, so everyone needs to pay attention to this.
