A “Covid passport” designed to help passengers avoid quarantine is being launched.

It will be used on Cathay Pacific flights between Hong Kong and Singapore from Wednesday, and on United Airlines flights between London Heathrow and New York next week.

The trial could be expanded to cover routes in Europe and Asia within three months.

The passport will be stored on a passenger’s phone and can hold test results to satisfy most of the varying travel restrictions around the globe.

Developed by non-profit trust the Commons Project Foundation, the passport requires passengers to take a coronavirus test before uploading results.

A negative feedback will generate a QR code that can be scanned by airline staff and border officials.

The digital passport will be able to contain test results and other health data required by any country and vaccinations.

Developer The Commons Project stated: “For global travel and trade to return to pre-pandemic levels, travellers will need a secure and verifiable way to document their health status as they travel and cross borders.

“Countries will need to be able to trust that a traveller’s record of a Covid PCR test or vaccination administered in another country is valid.”

Dr Bradley Perkins, chief medical officer of The Commons Project, said: “Without the ability to trust Covid-19 tests – and eventually vaccine records – across international borders, many countries will feel compelled to retain full travel bans and mandatory quarantines for as long as the pandemic persists.

“With trusted individual health data, countries can implement more nuanced health screening requirements for entry.”
