Many state issued IDs are now machine readable. I've had my ID scanned when I went to buy some beer before. I assume I trusted them to store it indefinitely, tying my real-world presence to my actual identity to comply with a law that is a minor hindrance to underage people wanting to access alcohol. (I don't know if the person who scanned my ID made minimum wage, though. Probably.)
