The state has started using an app that will give people the ability to show virtual proof of their COVID-19 vaccination.

The free app, called Docket, is also being used in Utah. Since last December, a record of each dose of the COVID-19 vaccines has been collected by the state's Immunization Information System.

"To be absolutely clear this is not a passport," Gov. Phil Murphy says.

Docket gives users access to that data. When asked whether Docket could be used by private businesses like restaurants or large venues to deny unvaccinated people access, Murphy did not offer a direct answer.

Officials say the cost of the app is being paid for by the federal government through the end of the year. After that, the state will pay between $8,000 and $10,000 a month to the company.

They also say Docket isn't allowed to sell your data. The Docket app is currently available on Apple and Google Play app stores.
