Readers for your kiosks (APPKiosk and WEBKiosk) can't only be imported automatically via CSV files or the API, you can also create them manually one by one.
First go to "My magazines"
Then click on "Kiosks" and "Members".
Now click on "Create".
Enter the basic user information and choose the access tags. These tags define what magazines the user can read. If you don't know how to create access tags go here
Also choose which WEBKiosks and APPKiosks the user can access. Done!
