After binding the mobile phone, change the password on the ATM, and the mobile phone can receive a message prompting the new password change.

Just handle the short message service. In order to ensure the security of withdrawal, a short message will be sent to the bound mobile phone that handles the short message service every time. Therefore, after the mobile phone is bound, the password will be changed at the ATM. As long as the mobile phone handling the short message service can receive the message, it will prompt the newly modified password. This is the SMS reminder function of the bank.
