According to the internal algorithm of the bank:
The frequency of swiping cards is high, which is equivalent to swiping cards on the same pos machine at least twice a month and will be recognized;
The amount of credit card is the same, for example, 3000 yuan per credit card is an integer, so it will be recognized;
The purpose of swiping a card is single, such as a hotel every time, and such a purpose may also be recognized;
The credit card limit is too large, such as 20 thousand yuan. If the one-time consumption is 19998 yuan, it will also be identified and monitored.
The time of swiping the card is the same. For example, every swipe is on the afternoon of the 7th of each month, which is monitored.
According to these rules and regulations, it is suggested that the consumption of credit card should not exceed 90% of the amount, and it should be used as reasonably as possible. If found out, the card will be lightly sealed. If the amount is too large, the bank has the right to sue for fraud.
