The UBS pos machine is not recommended for brushing after 10pm, after 10pm brushing is easy to be monitored by big data, causing wind control and leading to brushing failure.

When brushing cards, it is recommended to try to brush them during normal working hours to simulate normal consumption, for example: general shopping malls are open until the end of the 10:00 pm (except for entertainment venues), so it is recommended that it is best not to brush your cards after 10:00 pm at the latest every day.
