Transcript for 'Digital health passport' to open international air travel
and the pilot program that hopes to make travel safer and easier for airline passengers making trips overseas and ABC's gio Benitez is right here with details. Gio, good morning to you, sir. Reporter: Hey, Dan, good morning. We're talking about a sort of health passport. An app right on your phone that keeps track of all of your latest test results and the creators say this is exactly what is needed to restart international travel. This morning, a look at the new app hoping to change the way people fly from country to country. This week the first trial on a flight from London to Newark international airport. Passengers taking a covid test right at the airport. After 30 minutes and a text message, you've got a qr code that will verify your negative test results. Paul Meyer is CEO of the nonprofit group behind the free common pass app. We're building it as a common service for the world. That's why we're doing it as a nonprofit public trust because we really do feel like we're building something that is a common good. Reporter: The CDC have said they're encouraged by the common pass pilot program for that first flight this week. Enlisting volunteers to use the service, travel advisers robin and J.D. Took the test at London heathrow before flying to Newark. Basically you just showed your phone whenever you needed to prove that you had taken that test. Yes, yes. When I went to board the flight I scanned it right in and it gave the authorization that I was covid-19 negative. I felt much safer knowing that everyone around me had just tested. Everyone was negative. Reporter: It's not just test results. Meyer says the system is ready to eventually process vaccination records. What happens when a Vaine comes out? Is this app still relevant? Yeah, very much so because, remember, there's not just going to be one vaccine. There are many promising vaccine candidates. What that means is countries who are making this decision about whether or not to let people enter their country are going to need to know did this person get vaccinated, which vaccine did they get. Reporter: What about security? The group says they don't keep any of your medical information. They say it goes directly from the lab to your phone and they don't store anything in the cloud. By the way, again, this is just a pilot program from London to Newark at least for now, Dan. Gio, thank you very much.
