What are COVID-19 travel passports?These travel passes are intended as digital or paper certificates to be issued to travelers who have been either vaccinated against COVID-19, recovered from a COVID-19 infection, or recently tested negative. For instance, this is the case with the so-called "Digital Green Certificate", proposed by the European Commission on March 17, 2021. This idea, particularly supported by countries of the European Union whose economies largely depend on tourism, like Greece or Portugal, is to ensure safe travel across EU countries, without having to implement quarantine obligations or travel restrictions.
A similar solution, known as the "Travel Pass Initiative", has been promoted since late 2020 by the International Air Transport Association (IATA). This involves an app that would help passengers find test centers and receive test results and vaccination certificates via mobile, in order to easily show these documents via QR codes to the travel authorities prior to the trip. As both the EU and IATA’s proposals involve a travel app to manage personal data, it will be important to consider how to effectively keep travelers’ privacy safe. In this respect, a February 2021 survey revealed that the main concerns of travelers related to the use of digital health passports were linked to data and privacy worries.
