COVID passport ‘CommonPass’ starts trials this week

CommonPass, or a COVID-passport, is a technology framework that can be used by apps to verify an individual’s health status. It is being trialled by two airlines across a few sectors in the world. The system hopes to become a fail-safe way to verify a traveller’s health status and tally it against local entry laws. If it works, it could inspire governments to drop bans and quarantines.
