Walmart’s Use of Sci-fi Tech To Spot Shoplifters Raises Privacy Questions

But earlier this year, Walmart showed how times have changed. It tested a system that scanned the face of everyone entering several of its stores, identified suspected shoplifters, and instantly alerted store security on their mobile devices.
The potential of such facial recognition technology has been discussed for years. But now some stores are actually using it.
Walmart’s experiment, which it ended after several months, highlights the powerful high-tech tools available to retailers to reduce theft. However, it also raises questions about whether stores should have to follow rules when using the technology to protect shoppers’ privacy.
