Hello, there are many such calls, and you can receive several every day. Because I also use POS, the information may be leaked. POS machines with low rates generally skip codes and get more profits from third-party payment institutions, but it does great harm to credit card users and may be downgraded or even banned by banks.

Don't trust these calls, most of them are "phone calls". Now some people think that the funds will not be paid after the replacement. The installation of Ruiyinxin POS machine is completed by local agents, and users will not be notified by telephone.

Your good friend can't remember whether it started in August or June last year. The bank adjusted uniformly, and the POS machine rate was 0.6. It is recommended to use regular machines. The clearing machine is directly connected with the settlement of the bank.

This kind of phone is not a * *, but an excessive pyramid scheme, which has disturbed everyone's life. So after receiving this kind of call, you can directly refuse to answer or hang up. Don't talk too much with customer service, or you will be listed as a "potential user" and continue to be harassed.
