Why Are LGBTQ+ Bars Using PatronScan to Track Patrons?

• LGBTQ+ bars in San Francisco are using PatronScan, an ID-checking system that critics warn creates searchable databases of patrons rather than simply verifying age.
• California law generally prohibits businesses from retaining or using information from scanned IDs, except for limited purposes like age verification or fraud prevention.
• PatronScan retains standard customer data for 21 days and flagged data for up to five years, including names, dates of birth, photos, gender, and zip codes.

Concerns and Legal Context

• The California Senate Judiciary Committee previously investigated PatronScan, finding that it collected vast amounts of data and shared information between venues to maintain long-term bans.
• Privacy advocates argue that these databases threaten civil liberties by tracking where individuals go, who they associate with, and monitoring their movements.
• Immigration rights groups warn that labeling individuals as a "threat to public safety" within such systems could have severe consequences for their immigration status.

Industry Response and Recommendations

• PatronScan claims its systems are legal in California and denies using facial recognition or automated analysis of photos in North America.
• Experts advise that bars return to standard, visual ID checks, noting that these manual methods have effectively prevented underage entry for decades without creating secondary databases.
• Critics argue that businesses cannot claim to provide "safe spaces," particularly for vulnerable communities, while simultaneously feeding patron data into third-party tracking networks.
