You simply open the United App and hold the phone near the sign. The app then asks you for which pax you want to print tags and they pop out behind the counter. Was a lot faster than scanning BP at the kiosk. Took less than 30 seconds. Seems new as the staff were also saying how they learned about it today as well.
