Academic Info
This page is intended for all current HTWG Konstanz students. Here you can find answers to a wide range of practical and bureaucratic questions – ranging from your student ID and tuition fees to your internship semester.
Student ID / ZACK Card
Your “ZACK” card is your HTWG student ID. You can use your card to take books out of the library, enter certain buildings on campus, make copies, purchase food at the cafeteria (Mensa), and more.

Validating Your Student ID
Your student ID card will automatically be validated for your first semester. After that, you need to validate your ZACK card each semester.
You can validate your ZACK card in either the F-Building or the Library.
Lost or Defective Cards
In case you lose your student ID or the card is defective, just fill out the form below and turn it in at the registrar's office (Studierendensekretariat).
New / Lost Card request Form (in German)
A friend or family member can also pick up the card for you. To do so, just fill out the authorization form.
