You don't need to pay cash when you use a credit card, but you will pay back when the bill comes out. But try not to brush in the same place repeatedly.
There are some small habits in the use of credit cards, even if they are not cashed out, they will be mistaken for cashing out by banks, such as: swiping all the credit lines at one time, making one-time repayment, timing, booking machines, booking cards, making transactions, using fixed POS machines, swiping cards more than three times a day, and so on. Credit cards can be swiped several times a year, and there is no annual fee, but don't swipe them too many times on the same day, you can swipe them for several days.
