Mobile phone scan code poisoning, there has been a verification code SMS sent.

Because some QR codes are maliciously repackaged and implanted with viruses,

You can't see anything on the surface, but once you scan with the code scanning tool, it is possible to install and run these viruses. If you want to scan the code safely, you must use some tools, such as some mobile phone security software with security scanning function.

For example, Teng Xun Mobile Manager version 5.0 has updated and improved this function. You can try. There are no operation steps. Just open it before scanning the code. I hope you can be satisfied with my answer ~
