Vaccine passports and digital vaccination records, explained – Vox

A growing number of companies, health care providers, and state governments are launching their own efforts. New York released the first state-backed vaccine passport, called the Excelsior Pass, just last week. This digital health certificate, which IBM built using blockchain technology, allows people in the state who have been vaccinated or recently tested negative for Covid-19 to download their health records onto a smartphone app that displays a QR code, which can be scanned by participating venues to verify their status. That New York has spent months developing the Excelsior Pass shows some states didn’t expect the federal government to take the lead on key aspects of the country’s pandemic response.
