Students at the No.11 High School in Hangzhou are the first in the world to use facial recognition to pay for food at their cafeteria. Pupils order food on screens and pay for their meals by standing before facial recognition screens. Face data from each student is collected and stored into the school’s database. When students order food, the program compares their face to the database and automatically deducts money from their account. Students never have to bring cash or cards with them to school and payment becomes quicker and more efficient, but what do you think about the privacy issues?
