Wegmans is scanning faces at the door - and all it took to spark the backlash was the sign the law requires. A New York story about Wegmans using facial scanning to flag shoppers previously tied to misconduct kicks off a conversation about the cameras behind the screens.

David and Manny separate biometric surveillance from the anonymous computer vision most retailers already run, then ask what sensing actually helps content decisions in hotels, campuses, and stores that aren't ad networks.

In this episode:

• Compliant isn't comfortable: the signage is legally required, but there's no opt-out and no word on data retention. A surprising large number of US retailers already layer computer vision onto their loss prevention store cameras - tracking shapes and paths, not faces
• Newer tech like mmWave, can track dwell time, even heart rate: measuring engagement without capturing identity to see what actually changes behavior.

Big question: What would the sign at Wegmans have to say to make you stop shopping there? Where is your personal privacy tipping point for what stores and displays can know about you?
