The Australian government is planning to allow 90% of travellers to pass through passport control without human help by 2020. From a report: With a $100m budget, it has begun the search for technology companies that could provide biometric systems, such as facial, iris and fingerprint recognition. Head of border security John Coyne said it could be a "world first." But critics have questioned the privacy implications of such a system. "Biometrics are now going in leaps and bounds, and our ability to harness the power of big data is increasing exponentially," Mr Coyne told the Sydney Morning Herald. The department of border security hopes to pilot the "Seamless Traveller" project in Canberra this summer, with rollout to larger airports scheduled to be completed by spring 2019.
