Qantas is trialling a biometrics system that uses your face as your passport at Sydney International Airport. Participants will have their face scanned to prove identity, instead of a passport. In the future your face will be your passport and your boarding pass. Qantas customers will not only be able to check-in for their flight using the technology, it is also available for their lounge staff who can create a more personalized experience when you arrive. https://www.cnbc.com/2018/07/05/your-face-will-be-your-passport-qantas-passengers-start-using-biome.html?
