Top-ranking Republicans are trying to stamp out digital vaccine passports, that would allow businesses to check if customers are inoculated against COVID-19. The White House is working on a private sector-driven initiative to help businesses identify people that have been vaccinated, as venues reopen and travel begins to pick up. New York has already developed its own version, dubbed the “Excelsior Pass.” The digital app doesn’t display the user’s health information, and will be required for vaccinated customers to gain entry to large venues like Madison Square Garden.
