What does CCB SMS qxyx mean?

There are usually two kinds of check codes for banks. One is that when you enter a password, there is a separate check code box, which requires you to enter a check code and draw a number behind it to ensure that people are operating now, not machines;

Another common verification code is the SMS verification code sent by the bank to your reserved mobile phone during online banking, mobile banking and other transfer payment operations. You can directly enter the verification code box of mobile banking after receiving it. This is a way for the bank to guarantee your identity.
