A student card is your University Identity Document.
In order to have it issued, you have to pay 17 PLN to the account number given to you at the International Students Office of the University of Lodz. After you have done this payment, bring one photo (ID format) to the International Relations Office at our Faculty (Room C 133) . It takes 10 days to have it ready.
Your student card enables you to travel with the 50% discount and also to buy cheaper tickets to the cinema, theatre; some pubs and restaurant also offer lower prices to students. It is very important that you have it and not lose it!
