Your 'MultiCa' is your student ID card and public transport pass for the entire Rhine-Sieg Transport Association (VRS). Additionally, it serves as your library and copy card, can be used to pay in all university cafeterias and gives you access to the university lockers.

Name and design

The chip card’s design is determined by its technical requirements (position of the chip, validity imprint, etc.) and includes the university's corporate design as well as personal information on the cardholder.
