I.A.T.A. is one of several organizations that have been working on digital solutions to streamline the travel credentialing process for years; during the pandemic, these groups have focused on including vaccination status. The idea is that if you have all the pertinent information on your phone, a significant amount of time will be saved.

In addition to I.A.T.A., IBM has been developing its own Digital Health Pass that would enable individuals to present proof of vaccination or a negative test to gain access to a public location, such as a sports stadium, airplane, university or workplace. The pass, built on IBM’s blockchain technology, can utilize multiple data types, including temperature checks, virus exposure notifications, test results and vaccine status. The World Economic Forum and the Commons Project Foundation, a Swiss nonprofit group, have been testing a digital health passport called CommonPass, which would allow travelers to access testing or vaccination information. The pass would generate a QR code that could be shown to authorities.
