Cardholders use pos machines to swipe their credit cards, but there will be corresponding handling fees ranging from 0.8% to 1%, which are generally charged to commercial sellers. However, Bian Xiao does not recommend that you swipe your card with a pos machine at night, because pos machines generally cannot swipe their cards after 9: 00 every day at the latest. Therefore, POS machines try to swipe their cards during normal working hours.
