Why can't pos machines choose their own merchants? In fact, the function of POS machines to select merchants is contrary to the central bank's regulatory requirements for the financial industry, because POS machines are originally used for merchants.

Machines with the function of selecting merchants are generally used by some credit card holders to improve their credit card transactions and simulate consumption. Therefore, machines are usually in the mode of one machine with many merchants, and one machine with many merchants is the target of the central bank's clear and severe crackdown.

Therefore, the central bank announced the closure of self-selected merchants, with the aim of cracking down on multiple merchants with one machine, providing payment services for illegal merchants, applying low and zero-rate prices and transferring machines.

Although many people who do credit card transactions and credit card wool have been hit by the closure of self-selected merchants, at present, various third-party payment institutions are also improving and optimizing the function of automatically matching merchants as soon as possible, which can also help credit card traders to create perfect credit card bills, simulate real consumption, and achieve the purpose of increasing the amount and credit card wool.
