They also use them to flag people who've been previously banned and the systems work across venues. The idea that verification in the real world is cursory is not accurate.

The vast majority of places I frequent do not even have a person at the door checking IDs. If the bar tender/server thinks you look young, they ask for ID. I clearly do not look to be too young, so there's that. The last place I went to with an actual scanner was more of a nightclub that had a cover charge.

There's a fine line between night clubs and bars (and a venue can operate as both, depending on the night).

Functioning as a bar where people come in, drink and eat - generally not checking ID's at the door.

Functioning as a night club, generally checking ID's at the door. Almost no places I've been to scan ID's. I'm also middle aged and not going to night clubs hardly ever. Pretty much just a couple concerts a year in the big city. Those venues scan ID's.

Anecdotal evidence is weak (not) evidence.

		This is true but your orignal reply was also anecdotal.

		sure, but it is what it is. the places with scanners may be more sophisticated than i give them credit, but you cannot deny there are places that do not card every person every time you visit. online places will never not know it was you. if you cannot see the differences, then you're just deliberately being obstinate about it
