Blockchain-based COVID-19 passports to begin trials in Q1

The International Air Transport Association will soon roll out blockchain-based passports that digitally store an individual’s health information — specifically, their COVID-19 testing and vaccination status.

In a move which IATA says has the potential to reopen international and loosen current global quarantine restrictions, a “health” passport will be stored in a user’s smartphone in the form of an app, with the first real-world testing expected to take place as soon as February.
