The second cleaning machine refers to the pos machine after the second liquidation. The funds used by merchants to swipe their cards are not directly cleared to their bank cards through UnionPay or institutions with acquiring qualification (obtaining payment licenses issued by the central bank), but are cleared to other people's accounts and then remitted to their bank cards. In order to avoid the blow of law enforcement departments, some Qing Er POS machines can only be used for 1-2 months, and they will stop working within 3 months at most, which will cause great losses to users! In case there is something wrong with the money, think about where to cry first.
