A health passport is basically digital proof to show that the passenger is tested negative for COVID-19 or has been vaccinated against COVID-19 to facilitate travel. The health passport may bring quarantine-free travel in the future.
A health passport is also called a travel pass or a vaccine passport. Many versions of health passports are being trailed as of February 2021.
The purpose of a health passport is to provide airlines and governments that a passenger satisfies all travel requirements of the country and that the tests and vaccines are recognised by governments and the World Health Organisation.
It eliminates complexity, information gap and inefficiency by having a standardised app. The main goal is to ensure safe travel in the future and reassure governments that travellers are travelling without COVID-19.
