The scandal started when a student using the alias SquidKid47 posted an image on Reddit showing a campus vending machine error message, “Invenda.Vending.FacialRecognitionApp.exe,” displayed after the machine failed to launch a facial recognition application that nobody expected to be part of the process of using a vending machine.

“Hey, so why do the stupid M&M machines have facial recognition?” SquidKid47 pondered.
The Reddit post sparked an investigation from a fourth-year student named River Stanley, who was writing for a university publication called MathNEWS.
Stanley sounded alarm after consulting Invenda sales brochures that promised “the machines are capable of sending estimated ages and genders” of every person who used the machines without ever requesting consent.
This frustrated Stanley, who discovered that Canada’s privacy commissioner had years ago investigated a shopping mall operator called Cadillac Fairview after discovering some of the malls’ informational kiosks were secretly “using facial recognition software on unsuspecting patrons.”
Only because of that official investigation did Canadians learn that “over 5 million nonconsenting Canadians” were scanned into Cadillac Fairview’s database, Stanley reported. Where Cadillac Fairview was ultimately forced to delete the entire database, Stanley wrote that consequences for collecting similarly sensitive facial recognition data without consent for Invenda clients like Mars remain unclear.
Stanley’s report ended with a call for students to demand that the university “bar facial recognition vending machines from campus.”
A University of Waterloo spokesperson, Rebecca Elming, eventually responded, confirming to CTV News that the school had asked to disable the vending machine software until the machines could be removed.
