If there is a prompt that credit card transactions are too frequent, try again tomorrow. It may not only be because there are too many credit cards, but also because of the interval between two credit cards and whether the credit card merchants are the same. For example, a number of merchants have been swiped within half an hour, and this kind of card swiping behavior is easily restricted, and it is already in a state of semi-risk control of banks. It is suggested that when swiping the card again, it is best to standardize the use of the card. For example, don't swipe your card frequently in the same merchant, and the interval between swipes should be more than half an hour. You should also swipe your card during normal working hours, and you can pay in different ways, but you should pay attention to the matching of the amount of credit card and the type of merchant.
Bank card transfer is frequently marked as abnormal because the bank background thinks that the user's bank card is abnormal. In this case, the bank will generally take the initiative to contact the cardholder and inform him that the transaction is restricted because of frequent capital exchanges and suspicion of money laundering.
