In all cafeterias and Mensas of the Studierendenwerk Kassel you can pay cashless with the CampusCard. To do so, you must load an appropriate credit balance onto the CampusCard. If you study or are employed at the University of Kassel, you pay a lower price for your Mensa meal than guests of the university.
In order for your status to be recognized at the Mensa checkout and for you to be charged the reduced price, first have your Mensa status entered on the card at one of the so-called validation devices of the University of Kassel. If you have an older card (recognizable by the fact that the card number begins with a 3), please activate the wallet function once at one of the reload devices on campus.
