Korean universities are using campus IDs to make sure students don’t skip classes, according to a news report in the Chosen Ilbo. The IDs, which have been used to pay for meal and other functions, are also being used to swipe students into class.

Kyunghee University introduced its U-Class System in 2006. Students insert their ID cards in terminals installed in lecture rooms, their personal information is sent to the lecturer’s computer screen in real-time. By clicking a student’s photo onscreen, the lecturer can access the student’s number, attendance status, and participation rate.
