All of our members must own a Unioncard or a Campuscard. The Unioncard is available via dms.utwente.nl or the Sports Centre. The association fee also needs to be paid there. The prices of the Unioncard or Campuscard and the association fees can be found here.
If you do not own the card and/or have not paid the association fee, you will receive a fine. The money to be paid for a fine can be found here. On top of this fine, the association can also impose a fine of €25 for not possessing the card and for not paying the association fee.
