IBM and New York State have initiated the testing of their forthcoming blockchain-based Covid-19 digital health pass (Excelsior Pass), through which New Yorkers can securely display proof of a negative test result or vaccination certification.
A group of predetermined participants on Saturday used the pass to gain admission to the Brooklyn Nets basketball game at Barclays Center, while on Tuesday volunteers used it to enter a hockey game at Madison Square Garden.
The pass and its accompanying verification application are built on IBM's Digital Health Pass app, which employs blockchain to preserve privacy and let individuals store, manage, and share health status from mobile devices.
Users can either print out or store their pass on smartphones, and each pass features a quick response code for venues to scan with the verification app.
IBM's app also plugs into multiple data sources, and its open architecture will enable adoption by other states and organizations.
