I created a time lapse of people using the bag drop kiosk to check-in their luggage at the airport. After 20 minutes of time-lapse footage I checked the camera and realised I hadn't turned of screenlock so it automatically stopped after a few minutes. However, it worked long enough to record a group of three young people attempt to scan a mobile boarding pass using an Android device. They failed first time round and are recorded returning to the kiosk. I watched them personally and they ended up needing assistance. It transpired that because the user had the screen brightness turned right down there was not enough contrast for the kiosk to read the barcode.
