At present, POS machines intelligently match merchants according to the use area. As long as it is a local merchant, we don't have to care too much about the problem of credit card bill merchants. Almost, no problem. If it is not local, the impact on credit cards can be large or small, depending on how users use it. First, banks can't monitor the actual location of users. He doesn't have the ability to monitor, and he doesn't know the exact location of the business you brush.

The merchants you brushed out are all across provinces, such as the first Beijing, the second Shanghai and the third Guangzhou. If the time interval is too long, it will trigger the wind control system. Under normal circumstances, banks will send SMS reminders, which will not directly control the risk of your card. In the process of using POS machines, we don't have to pay too much attention to the landing problem of merchants, and the matching merchants are basically in a range.
