Hundreds of stores from Walgreens to Macy's are silently deploying facial recognition technology to spy on shoppers (and it's legal in most states)

Major retailers in the US are already using facial recognition cameras to spy on shoppers, a campaigning group has warned. The tech - usually associated with authoritative regimes like China - is being used both to identify shoplifters and serve'personalized' adverts. Caitlin Seeley George of anti-face recognition campaign group Fight for the Future told DailyMail.com Walgreens and Macy's are among the largest retailers to adopt the technology, deploying it in hundreds of stores across the country. And it is not just America - Britain is also adopting the tech.
