How do campus guards enter their mobile phone numbers?

The invention relates to a method for campus security to input a mobile phone number, which is realized by the following steps:

Step 1: Open the campus guard application. On the main interface of the application, there is usually an option of "Personal Information" or "Settings".

Step 2: Click to enter the personal information or settings page. On this page, there is usually an option of "mobile phone number" or "contact information".

Step 3: Click the option of mobile phone number or contact information to enter the editing interface of mobile phone number.

Step 4: In the mobile phone number editing interface, an input box will appear. You can enter your mobile phone number through the keyboard.

Step 5: After entering the mobile phone number, click the Save or Confirm button to complete the mobile phone number entry.

The reason for entering the mobile phone number is to establish contact and communication channels. Campus guards need students' mobile phone numbers in order to contact students or their parents in time in case of emergency. For example, if there is an emergency or a student has an accident, campus guards can get in touch with students or their emergency contacts quickly through their mobile phone numbers and take emergency measures in time to ensure the safety of students.

In addition, entering the mobile phone number can also facilitate the daily management and service of campus guards. Campus guards can communicate with students through mobile phone numbers, such as informing students of activities and reminding them of matters needing attention. At the same time, students can also ask questions, reflect opinions or seek help from campus guards through their own contact information.

Therefore, the purpose of entering the mobile phone number is to establish an effective communication mechanism to ensure campus safety and provide convenient services.
