In New York State's announcement, the state outlined links for businesses and consumers to opt into Excelsior Pass. Madison Square Garden will begin using the technology this week. Other venues are expected to follow once smaller arts, entertainment, and event venues are eligible on April 2.
Given that New York is the first to use the technology, you can expect other states to follow as they open venues and aim to bring back crowds 100%. Private companies may require documentation and the app approach will make it easier to share information to gain entry.
Why will this technology be more accepted? Here are a few reasons:
States want to reopen, and IBM's federal and government unit has a white-label technology and installed base. I'm also betting that, if consumers can control their data and do it in a secure way, they'll go for the trade-off between vaccination for access. Excelsior Pass is only accepted in New York for now.
Regulations may dictate that events like weddings and social events can have larger numbers if people are vaccinated.
The vaccine passport interface is familiar -- a QR code system that will be familiar to anyone who has used a mobile boarding pass.
Other countries are already going the vaccine passport route as are airlines.
Major labs have committed to rapid reporting of COVID test results so people can get results in time for a start of an event.
And ultimately your employer is likely to want to verify COVID-19 test results and vaccination status. Companies aren't likely to build their own apps for a bunch of reasons but can piggyback on state, government. and consumer-endorsed vaccine passports.
