Your student identity card is your identification when you are on campus or need to document that you are enrolled at Aarhus University. Especially at exams it is important that you bring your identity card and you can also use it to get student discounts at museums, cinemas etc. The ID also functions as a keycard and gives you access to buildings outside normal hours.
At the beginning of your studies at AU it is important that you get a personal student identity card. It is only possible to get the card after you have been enrolled at AU and hence have been assigned a personal matriculation number. Enrolment of students is an ongoing process that starts after the application deadline.
