Walmart is using AI-powered cameras to prevent theft at checkout lanes

Walmart has been surveilling its checkout registers using a computer vision technology called Missed Scan Detection to identify when items move past the scanner without having been scanned. As reported by Business Insider, the technology has been implemented in more than 1,000 stores across the US over the past two years, and it monitors both self-checkout kiosks and traditional registers managed by human cashiers. The system runs on cameras that watch as items move across the register. If an unusual activity occurs, such as an item moving into a bag without being scanned, a checkout attendant will be notified to take action. Missed Scan Detection was designed to help reduce theft and other losses, a problem that has cost US retailers up to $47 billion in 2017.
