Restaurants, hotels and other hospitality venues will be fairly straightforward as its just an extra part of the "check in" process. How it might work in places like shops and public transport though where the foot flow tends to be much greater I don't know as it's hard to see how they would staff that.
I'd imagine it will be more similar to MOTs for cars. First check if they live in the country then check if they're vaccinated. If they aren't the fine is automatically sent and then follow up a couple of months later with further fines/convictions etc.
You can't rely on shops and businesses to enforce vaccinations.
