Launch of New Facial Recognition in UK Shops Prompts Backlash
The system will alert police in about four seconds after a match and is being expanded to more than 100 stores as shoplifting rises.
A facial recognition system in more than 100 UK shops is launching a feature that alerts police instantly when flagged shoppers enter stores, with alerts arriving in an average of four seconds.
Retailers like Sainsbury's are accelerating facial recognition deployment to combat surging theft, which exceeded 509,000 offenses in England and Wales in the year to December 2025.
Evidence suggests the technology misidentifies Asian and black people more frequently than white shoppers, while Big Brother Watch warns the system relies on "secret blacklists" compiled by private security guards.
Facewatch processes data through Amazon Web Services, the same infrastructure powering a controversial $1.2 billion contract supplying the Israeli military, sparking human rights concerns among campaigners.
Sainsbury's plans to expand to 200 locations by the end of 2026, yet regulation lags behind deployment; Nuala Polo of the Ada Lovelace Institute warns private firms face fewer restrictions than police.
