Indeed, there is a tool that can distribute cards under control by the dealer.
There's really no assurance that virus cannot be passed even wit an automatic card dealer machine, there's still always an instance that other players might touch your hands, or the dealer to check it. Unless they have sanitizers nearby that they can use every time to make sure that they always kill the virus. Remember, COVID isn't just transmitted through the mouth, if someone touches their eyes, they can still acquire it.
New Normal betting I think is possible with Slots and games which aren't requiring any physical contact with other person.
The most infections of COVID 19 happens through the air with small liquids. The spreading of corona virus through smear infection is fairly limited. Sanitizers and washing your hands regularly is the key. It's hard to control your body for a long time to touch your face so it's better to make sure your hands are clean of the virus. Also, just you touch something quickly infected by corona doesn't mean you are instantly infected. It seems to be taking a longer period of time. I heard that exposure of atleast 5-10 minutes increases the chance of a succesfull infection dramatically.
