The Student Card is non-transferable.
It is used for access to the university buildings, as a user card for the university library and as a cashless means of payment on campus (unibar, photocopiers, library and university canteen).
If you have duly paid the tuition fees, the validity is automatically extended (see my.scientificnet.org).
If your card does not work:
You can request a new card at the Student Secretariat. The cost to replace a card is € 20. Any credit you had on your old card will be transferred to the new one.
