The correct way to raise a credit card: 1. Be sure to accumulate credit and repay it on time three months after opening the card. Let the bank absolutely rest assured that it takes more than three months for the bank to withdraw the amount and six months for the card to be used. These are all used to see your performance. Only when you have maintained a good credit record in the past few months can the bank withdraw the amount and use the card to handle the card.

2. Brush as many small pos machines with points as possible. Only when the bank makes money will the bank give you an increase. The profit of pos machine is divided as follows: issuing bank 7, deposit bank 2, UnionPay 1. Those with points are not capped, and those without points can't make money.

3. Pay back the money frequently. The purpose of this is to increase the efficiency and increase the utilization rate of funds. The more frequently you pay back the card by swiping it, the more banks like it. Only in this way can banks feel that their funds are safe and can make money.

4. For friends who want to cash in working capital, please read this article. Banks believe that the key to cashing out is large-scale consumption-large-scale whole-in and whole-out, and the overdraft amount accounts for a high proportion of the total amount and lasts for a long time, which is a big taboo for using cards. In fact, it doesn't hurt to cash out. This is a problem that every bank can't solve. The key is not to go too far. My own suggestion: you must be careful when you brush a large amount, and the amount should not exceed one-fifth of the total amount. Except brush integral.

5. Take every opportunity to brush every day, big or small. I will swipe my card when I buy a bottle of mineral water myself. What to pay for electricity, water and telephone? Don't underestimate these small credit card records, which are very useful for your card activity. Credit card amount, credit card frequency, consumption type, repayment record and credit card contribution value? These are the categories of bank computer system inspection.

6. Withdraw cash at least twice a month to make the bank earn some interest. Do it in installments every two months, and the number of installments should not be too long.

7. Participate in the preferential points activities of the bank.
