The student card is the size of a credit card, but it can change your life. Not only does it confirm your student status and allow access to libraries and other HEI facilities, but it also entitles you to all kinds of student discounts, most important of them being a 50% discount on public transport (saving you up to EUR 15 every month). There is also – up to age 26 – a 37% discount on national railways, allowing you to travel all around the country for less. Some other transport companies, as well as theatres, museums and cinemas, even restaurants, have special prices for students. In some HEIs, the student union provides additional discounts for students.
So get your student card and enjoy the city!
