Handwashing Detectors are Coming to Restaurants

Employees wash their hands, then place them under the device's scanner.

The food industry is fighting germs with a new tactic called the “hand-scanner” and it’s basically a lie-detector at the sink. A tech start-up in New York created a product to help keep hands clean. Employees wash their hands, then 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 their hands again and go for another scan. Managers can have employee ID codes linked to the scanner so they know who has clean hands. According to the CDC, most food workers wash their hands about a third as much as they should.
