A debate is growing around the use of facial recognition technology in UK shops.
Reports say Facewatch, a facial recognition system used by more than 100 businesses, plans to launch a feature that can alert police when serious flagged offenders trigger a live facial recognition match.
Supporters argue that this kind of technology could help retailers respond faster to repeat theft, abuse, or violence in shops.
However, civil liberties groups have raised concerns about surveillance, mistakes, and the lack of stronger regulation around this type of technology.
This issue matters because it sits between two major public concerns: safety in shops and personal privacy.
Would you feel safer if shops used this technology, or would you feel uncomfortable being scanned while shopping?
