Connecticut is launching a new app that will allow you to input your vaccine information for your convenience, but not all businesses are thrilled with the idea.

Some restaurant owners say they are worried this could lead to a vaccine mandate.

To be seated at Oishi Sushi & Izakaya, you don't need to be vaccinated.

"To check every individual on the vaccination card, it's going to be time-consuming," says owner Chris Chen.

In Connecticut, only a handful of restaurants require vaccine cards. Those that do will soon have a new option -- a smartphone app much like New York's Excelsior Pass.

"I think it's probably a good thing because worrying about carrying around a paper card, and all the misinformation of people faking them and stuff," says Ryan Hoffman, of New Canaan.

Gov. Ned Lamont insists this will not lead to a vaccine mandate.

"I believe him when he says that in the conversations. And I think, you know, he's understood that over the last, probably what, eight months since New York City announced their vaccine mandate, and the challenges that's caused," says Connecticut Restaurant Association President Scott Dolch.

Critics say an app will only encourage businesses to impose their own mandates.

"It would concern me if a grocery store in a rural area that is the only access for people to get their groceries denies people access to that building based on their vaccination status," says Connecticut House Minority Leader Vin Candelora.

That's not a concern at Oishi. It plans to keep its doors open to everyone.

"As of now, probably not going to change the policy until that's broadly available," says Chen.

Oishi says it'd actually support a vaccine mandate if it applied to everybody, but Lamont says he has no plans for that.
