The Commons Project and the World Economic Forum are piloting an initiative right now called the CommonPass framework, and a number of airlines, including Lufthansa and Swiss International Air, are expected to start rolling it out before the end of the year.

What the CommonPass does is allow people and travelers to verify their health status via a digital certificate on their phone. Right now it can confirm that you've tested negative for COVID-19 and eventually it will confirm if you've received a valid vaccination.

The framework also asks countries to publish their travel entry criteria in a standard format, so that it's easy to update and it can be globally understood.

Of course, much like all of the exposure alert apps that are out there, this is only really useful if people and companies actually start using it. But the travel industry knows that for customer confidence to return, people are going to need to feel safe again. And a digital health pass is one way to help with that.
