Have you ever felt discomfort in the classroom when professors call more than 60 students’ names? Until last year, professors called everyone’s names before the class started and it took more than five minutes, especially when the number of students exceeded 100. Some professors tried to put numbers on each student in order to shorten the time calling everyone’s names. However, for the first time at Korean universities, Chung-Ang University started using a mobile E-ID to check attendance by using a barcode and ID Card. Let’s look more into it.

           At the front and the back of the classrooms, there are card readers on the wall, and there are two ways you can utilize them. First, you can access the CAU E-ID Mobile Application and show your own QR Code after you press the camera button on the terminal. The camera recognizes your code and checks your attendance. Second, you can just clap your ID card over the card leader. However, you can also do it simply by just sitting on the chair. After you log in to the E-ID mobile application, just slide the screen to the left, and then you will find the attendance button. Just push it, and just remember that you can start check-in ten minutes before the class starts.

           It’s very time-effective since the professors can start the class more stably and quietly. They can also make the time limit that the attendance takes to allow the class to flow more smoothly. However, some professors and students are worrying about misconduct, such as going out from the classroom secretly during the lecture, or proxy attendance done by friends. We should look after this service and give feedback in order not to abuse this new system.
