Yeah, but the bar bouncer doesn't keep a registry of a million different customers and profit from selling my info.
I wonder if there could be some sort of NFC/USB Yubikey thingy that resides in your government-issued ID that responds with TRUE if the person is considered an adult. Ideally, it would just leak your nationality (the "is_adult=true" response would be digitally signed by your government at ID-issuing time).
