When the Supermarket Recognises You: Machine Vision’s Test at the Shop Door

UK supermarket chain Sainsbury’s use of facial recognition is part of an international shift towards cameras that trigger action.

The retailer says facial recognition is operating in 40 stores, with plans to extend it to up to 200 by the end of 2026.

NIST’s facial recognition evaluations explain that poor lighting and camera angles can contribute to missed matches and demographic differences.

Facial recognition is therefore one element of a broader visual security strategy, rather than a universal answer to retail losses.
