Why Do Vending Machines Have Facial Recognition Technology?

A month ago, the University of Waterloo in Ontario, Canada became a subject of intense controversy over facial recognition — because of a vending machine.

A student came across a "smart vending machine" on campus that was malfunctioning. An error message on the machine's display screen said "Invenda.Vending.FacialRecognition.App.exe," indicating the use of facial recognition.
