Tech Companies Are Racing to Build Smart Vaccine Passports. But Technology Isn't the Only Problem
Countries around the world are considering a way to allow citizens to have access to a global "vaccine passport" to show their vaccine status, specifically the COVID-19 vaccine. Among those leading the way, the Estonian, Hungarian, and Icelandic governments have all signed up to pilot a technology that would allow people who have received the vaccine to prove their health credentials at the scan of a QR code. VaccineGuard is being piloted as part of an agreement signed between Estonia and the World Health Organization (WHO) last October, to collaborate on developing a digital certificate of vaccination that would work across borders, also called a "smart yellow card."
