Oh in Japan I saw a beer vending machine that had no age verification just on the street near my hotel. As an adult it was great since I was jet lagged and tired from a day of work, but I was also hitting up the conbini anyways so I defaulted to getting my beer with my onigiri
I have seen vending machines for beer that you have to swipe your passport/ID on so that it verifies your age. So ething sinilar could be done
Any smoke/beer vending machine ive seen has always been in an establishment you need to be 21 to enter (bars/clubs) and they check ID at the door
That one was at a bus stop in Germany
