Fast-food chains to use hand-washing lie detectors

(CNN)– The food industry is fighting germs hand over fist. It’s called the “Handscanner” and it’s basically a lie detector at the sink.

The product from “Pathspot”, a tech start-up in new York lives up to its name. After employees wash their hands, they place them under the device’s scanner.

The hand scanner looks for dirt of any sort on the skin and gives results within seconds.

If germs are still present, the employee will be prompted to wash his or her hands again and go for another scan.
