Australia Sydney airport

Australia Sydney airport tried to launch a new facility for the Qantas passengers to travel in whole world without taking passport. If they are successful in his work so it's very good for us .

They identify our face recognition and our finger prints and all biometric. Lots of peoples are talking about its not good for our privacy. It will be done his work fully proffered without any risk . It's very good because if we are carried out identity like our face, eyes and finger prints so why we carried I'd card . This concept will done with 100% may be it will run in whole world.
So please do comments how to like this concept.
