How do I select a checkpoint?

First select the corresponding event.

Select checkpoint I

Now select the checkpoint at which you want to scan.

Select checkpoint II

The selected control point is later greyed out and also marked in the settings for the selected event.

You can also set control points later via "Settings" under "Select control point".

Select checkpoint III

Scan at the wrong checkpoint

If tickets are scanned at the wrong checkpoint, an error message appears.

Select checkpoint IV
