Facial recognition cameras arrive in UK school canteens
Advocates say they speed up queues, but privacy campaigners query whether they are necessary.
Facial recognition computers have found an unlikely new niche: scanning the faces of thousands of British pupils in school canteens.
On Monday, nine schools in North Ayrshire will start taking payments for school lunches by scanning the faces of pupils, claiming that the new system speeds up queues and is more Covid-secure than the card payments and fingerprint scanners they used previously.
