In a move that sounds convenient and a little terrifying, international travelers to Australia may not need a passport by 2020. Officials say that the country is implementing a system to replace the standard paper ID with biometric technology that recognizes faces, irises and/or fingerprints.
If all goes to plan, passengers from other countries will arrive in Australia and walk directly out of the airport just like a domestic traveler. The goal is to have 90% of arrivals passing unmanned electronic stations without hassle some time between 2019-20. A human would only need to get involved in the event of a travel restriction or technical issue.
