Amid tech backlash. Several US banks have started deploying camera software that can analyse customer preferences, monitor workers and spot people sleeping near ATMs, even as they remain wary about possible backlash over increased surveillance, more than a dozen banking and technology sources told Reuters. Previously unreported trials at City National Bank of Florida and JPMorgan Chase & Co as well as earlier rollouts at banks such as Wells Fargo & Co offer a rare view into the potential US financial institutions see in facial recognition and related artificial intelligence systems. Widespread deployment of such visual AI tools in the heavily regulated banking sector would be a significant step toward their becoming mainstream in corporate America.
