As the continuous developments and wide applications of the smart mobile terminals, this paper studied and designed a digital orientation system. The system changes the traditional cumbersome register process. Using the system, students can pre-register on the internet or mobile terminals like mobile phones. Works such as personal information perfection, green channel application, tuition and fees payment, voluntary purchases on articles of daily use and uniform for military training, information registration of arriving at the university, classmates check, registration sheet print and so on can be done all at once without leaving home. The system can really help new students and their parents experiencing "one-stop" services. And all kinds of statistics reports can improve the efficiency and service level of orientation management greatly.
