All the times I've bought alcohol, tobacco and most non-opiate prescriptions anywhere they always type it in but I wouldn't really care if they did scan it.
HOWEVER, trolling people in real life is also incredibly fun so I'd bring my passport for gits and shiggles because it's the single most valid form of ID you can have while at the same time their system is probably only set up to scan state IDs
