Biometrics to replace passports in Australian and US airports
The Australian government aims to automate 90% of air traveller processing by the end of the decade in a shift that will require a radical rethink of security procedures. Under the proposed system, incoming passenger cards will be abolished and passport control officers will be replaced by automated stations. Passengers will then be processed using biometric recognition systems rather than passports. The country's government hopes that biometric processing will allow international passengers to walk out of an airport in much the same way domestic ones can. However, it's not yet known how the government plans to implement the necessary recognition systems.
International passengers would be whisked through immigration and customs without stopping or even encountering humans, while passport scanners and paper cards would be a thing of the past, under a radical overhaul of Australia's airports due to start this year.

The Department of Immigration and Border Protection has sought technology that would abolish incoming passenger cards, remove the need for most passengers to show their passports and replace manned desks with electronic stations and automatic triage.

The plan goes much further than the SmartGates currently installed at some airports that require passports to be scanned electronically. Those gates, introduced less than 10 years ago, will be retired as part of the new "contactless" system.

Instead, passengers will be processed by biometric recognition of the face, iris and/or fingerprints, matched to existing data. By 2020 the government wants a system in place to process 90 per cent of travellers automatically, with no human involvement.
