Visiting another country? You will need a passport and, probably, a digital vaccination document. Hoping to restore international travel, the European Union, some Asian governments and the airline industry want to create a vaccine passport. They are working on systems for travelers to use phone apps to prove they have been vaccinated. This will help travelers avoid local quarantine requirements when they arrive. The various efforts, however, show the lack of a central international system to check on vaccinations, either electronically or with paper documents. There are also questions about privacy and vaccine inequality. But many countries want them. The European Union (EU) and countries like Iceland have opened their borders to vaccinated visitors. Saudi Arabia will soon start permitting its vaccinated citizens to travel to foreign countries. Here is a look at how vaccine passports might work: The EU, China and Japan are working on their own digital vaccination documents for international travel. Britain updated its National Health Service app last week to let travelers prove they have been fully vaccinated. It comes just as travel rules are easing. The EU is testing a digital document to confirm COVID-19 test results or recovery from the virus. It is to start by the end of June. It is still unclear where and how exactly travelers in the EU will have their vaccine documents checked since there are no borders. Officials in Brussels say that question will be decided by each country. The idea is that travelers will show a QR code on their phones so it can be inspected at an airport or train station. Officials will check it against national databases. Travelers also need a phone app to show an official vaccination document. The EU’s project includes free technology European countries can use to build their official documents. The airline industry organization, the International Air Transport Association, has its own IATA Travel Pass. Airlines including Qantas, Japan Airlines, Emirates, British Airways and Virgin Atlantic have agreed to use the app. CommonPass is another app being used by Cathay Pacific, JetBlue, United and Lufthansa. Right now, Travel Pass and CommonPass are only available to travelers on airlines that are using them. Both can be used with airline travel apps, so users can show they have been vaccinated when they check in online. Both also plan to be used with EU vaccine documents. CommonPass says users will be able to put in their vaccine information by mid-June. CommonPass head Paul Meyer said vaccine passports will only become more common. “Our expectation is it will remain a requirement for international travel,” he said.
