POS code trading has a long history. Many POS agents and merchants tamper with the types of merchants at will in order to pay a small amount of fees, which leads to market confusion and the rights and interests of card readers are not guaranteed. In response to the new market violations, UnionPay once again issued the "Implementation Rules for Restricting the Acceptance of Market Violations by UnionPay Cards" (hereinafter referred to as "New No.5 Document"), which will be implemented this year. POS machine violations can no longer be willful!

Card issuers are included in the scope of violation punishment.

In the process of rapid development of M&A market, chaos is surging.

Many cardholders may encounter this problem. After receiving the monthly credit card bill, they found that several transactions did not match their actual card contents. Obviously, the risk management of pos machines, this restaurant is eating. In the supermarket, KTV singing became a gas station, and jewelry store consumption became a training school. These are code transactions that UnionPay and even many banks hate, that is, "changing clothes".
