Eight schools in North Ayrshire, Scotland, have “temporarily paused” use of facial recognition scans for payment in cafeterias, while one has completely abandoned the option, ZDNet reports. More schools were expected to follow the facial recognition use, which raised concerns from privacy advocates. The U.K. Information Commissioner’s Office also intervened to see if a “less intrusive” option was possible. The North Ayrshire Council said it is reverting to the previous PIN number system “while we consider the inquiries received.”
