The explosion of credit cards means that the actual consumption amount of credit cards exceeds the amount of credit cards. Bank credit card overdraft refers to the maximum amount of overdraft consumption and cash withdrawal approved by the bank according to the cardholder's income and credit status, and the cardholder can recover it within the validity period of the credit card.

In order to avoid the explosion of credit cards as much as possible, a better way is to increase the quota. Pay attention to the following points when increasing the credit card limit:

1. Always use a credit card, regardless of the amount, as long as you can swipe your card, you will definitely swipe it.

It is best to spend at least 30% of the bill every month.

3. The credit card bill takes three months, and it can't be broken in the middle, that is, it needs to be spent every month.
