Several companies and technology groups have begun developing smartphone apps or systems for individuals to upload details of their COVID-19 tests and vaccinations, creating digital credentials that could be shown in order to enter concert venues, stadiums, movie theaters, offices or even countries.

The Common Trust Network, an initiative by Geneva-based nonprofit The Commons Project and the World Economic Forum, has partnered with several airlines including Cathay Pacific, JetBlue, Lufthansa, Swiss Airlines, United Airlines and Virgin Atlantic, as well as hundreds of health systems across the United States and the government of Aruba.

The CommonPass app created by the group allows users to upload medical data such as a COVID-19 test result or, eventually, a proof of vaccination by a hospital or medical professional, generating a health certificate or pass in the form of a QR code that can be shown to authorities without revealing sensitive information. For travel, the app lists health pass requirements at the points of departure and arrival based on your itinerary.
