But stores will still use facial recognition to track how long you linger in front of the baked bean section of the shelf. Got to have priorities.
They don’t use facial recognition for that, just proximity sensors / BLE sensors. I installed about 4,000 of the BLE sensors in a hospital in Indiana last year as they had contracted to develop a phone app (Apple IOS and Android) to include location detection, way-finding, and points of interest throughout the hospital complex. It was pretty neat - but doesn’t do “facial” profiling, it does do “device” profiling, because it knows the MAC address of your device as it travels through the map, and moves you along your route.
That, but not how long one lingers in front of the ethnic hair care products...
