Credit limit: We must cherish the credit limit and never default on the bank's money, because the bank's money cannot be delayed for a minute. It's better to pay back early than to default on the bank. If the credit is delayed, the credit will decline, which will cause a lot of trouble.

Second, cash withdrawal: Try not to withdraw cash by credit card or invest with the money in credit card, because the interest and handling fee of cash withdrawal by credit card are very high, so it is good to make money by investing. If something goes wrong, how can I pay back the money in my credit card?

Third, credit card habits: we must develop a good credit card situation. No matter what the amount is, you can pay by credit card. It's best to spend this money in some places where you can make money, such as helping others in an emergency or purchasing in the country's foreign trade. Earn 1.2% in 30 days is still very good.

Four. Raise the card with the card: It is recommended that the cardholder apply for the card early and raise the card early, instead of temporarily applying for the card when necessary. Even if the quota is handled, it may not arrive soon. You can pay more attention to raising cards and increasing the credit card quota when spending at ordinary times, and you can also set up cards with cards later.

Verb (abbreviation of verb) points: You can get corresponding points by swiping your card, and the points can be exchanged for dependent gifts or benefits in the corresponding app of the bank.
