Bars are scanning customers' IDs and tracking their unruly behavior to build a massive, secret nationwide database of banned patrons—the "nightlife equivalent of a no-fly list." Important reporting by @susie_c:  https://onezero.medium.com/id-at-the-door-meet-the-security-company-building-an-international-database-of-banned-bar-patrons-7c6d4b236fc3 

This startup allows bouncers to scan your ID at the door to see your past "transgressions" before deciding to let you in. Run afoul of one employee at one bar, for whatever reason, and you could be banned from bars across the country for years to come.  https://onezero.medium.com/id-at-the-door-meet-the-security-company-building-an-international-database-of-banned-bar-patrons-7c6d4b236fc3 

Police are already requesting access to the database of banned bar-goers, which PatronScan grants without a warrant.

A nightlife blacklist has obvious appeal for bar owners. But experts say the system raises serious civil liberties and discrimination concerns: "When you create a confidential ban list, that’s an invitation for businesses to pretextually exclude people because of who they are.”
