A student has his face scanned to make payment at the dining hall of No. 11 High School in Hangzhou City, capital of East China’s Zhejiang Province, Oct. 12, 2017. Students do not need to pay in cash or swipe a card to buy food, but instead stand in front of a webcam for one second to finish payment using facial recognition technology. The system also collects data and a report on the student’s diet will be sent to their parents once a week rather than once a month in the past. (Photo/VCG)
