Check-in via Hansefit-ID. To call up your Hansefit ID, go to your profile and click on "Show Hansefit ID". Alternatively, you can also call up your Hansefit ID via the check-in area. Your Hansefit ID is displayed in the form of a QR code. Hold this QR code over the scanner provided at the entrance. Please note that you must retrieve your Hansefit ID directly via the Hansefit app. A screenshot of the QR code will not work.
