Sainsbury’s 'dangerous' facial recognition is back, months after ejecting an innocent shopper
Sainsbury's has reactivated facial recognition technology in its stores, months after the system reportedly led to an innocent shopper being wrongly ejected. The retailer is pressing ahead with the surveillance despite criticism over its earlier misidentification.
Why this matters: Facial recognition in supermarkets means your face is scanned every time you shop, not because you did anything wrong, but because you showed up. When a system like this already got someone thrown out who should not have been, resuming it without a public explanation of what changed is a problem. Shoppers have no real way to opt out. They also have no way to know how their biometric data is stored, shared, or used. Restarting a system that misidentified someone is a choice. It deserves a clearer account of why.
