Main concerns related to digital health passports among travelers worldwide 2021

As the coronavirus (COVID-19) pandemic disrupted normal travel in 2020, several countries started to discuss the introduction of digital health passports in 2021, aiming to facilitate travel during the health crisis while minimizing the risk of spreading the virus. These passes were intended to be digital certificates issued on mobile apps to travelers who had been vaccinated against COVID-19, recently tested negative, or recovered from a COVID-19 infection. A February 2021 study asked travelers worldwide about their main concerns related to the use of digital health passports. Roughly 38 percent of respondents expressed concerns linked to security risks with personal information being hacked. Meanwhile, 30 percent of the survey sample was worried about the lack of transparency and control over the shared data.
