Sainsbury’s to Expand Facial Recognition Surveillance to 150 Stores

The current rollout follows a pilot program across 55 sites. The mechanism allows retailers to upload reports of shoplifting or violent behavior, which are then verified by moderators. When a person matching a flagged profile enters a store, staff receive an immediate alert via the Facewatch system.

Despite the retailer’s confidence in the technology, the deployment has faced scrutiny following an incident in South East London. A customer was incorrectly identified and ejected from an Elephant and Castle branch, an error the company attributed to a staff misidentification rather than a technical failure. Sainsbury’s stated that this was an isolated human error and maintained that the Facewatch software has not incorrectly identified any individuals to date.
