All travelers who want to fly to the U.S. are required to present proof of negative Covid-19 tests. For now, proof takes the form of a printout of a test result or a photo of the result — creating opportunities for misunderstandings or potential fraud. Newly launched digital initiatives hope to clear up any ambiguity, standardize information and share the information securely.
International travel is likely to be the first industry to use new digital passports. One of the first flights to trial a new "digital passport" embedded with vaccination information and test results took off Thursday morning, a Qatar Airways flight from Doha to Istanbul.
