Recently, my friend's personal letter asked: Will credit cards explode every month? The following is Bian Xiao's introduction.

If all cards are used normally, there will be a consumer market every month, and the explosion of credit cards will not be easily controlled. In the end, the real consumption will reflect the spending power of card users, and financial institutions can earn service fees. Of course, financial institutions are very happy, not only are they not easy to control, but they may also increase the fixed amount.

On the contrary, if cards are used abnormally, credit cards are not used at ordinary times. After the explosion every month, It is remarkable to receive the email notice from financial institutions, especially the following personal behaviors of using cards, which must be warned.

1. The amount of printing cards spans a lot: some people usually print dozens or hundreds of cards, and suddenly they are abnormal, always printing more than 1, cards, or even more than 1, cards, and printing cards at one time is an industry without points. The probability of printing cards is very high.

2. Abnormal working hours cards: The normal business hours of many stores are from 8 am to 1 pm, and no later than 11 pm. If you print cards in the middle of the night, you will print 1, cards at a time, and if the types and amounts of printed cards are inconsistent, you will not care once or twice. If the frequency is too high, the system software will detect the abnormality of the cards. It will also be controlled.

3. Cards are often printed on third-party POS machines: Now many POS machines are fully automatic matching operators, but the terminal equipment number of each POS machine is unique. No matter how many operators are changed, there is only one terminal equipment number. Financial institutions know what you are doing.
