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.
