SHENZHEN -- On a weekday morning in late June, children stand outside the entrance to their elementary school in Shenzhen, Hong Kong's mainland neighbor. A line of gates equipped with facial recognition technology keeps out intruders and notifies parents via smartphone that their kids have arrived.
The facial recognition system was developed by Shenzhen-based internet giant Tencent Holdings and is just one example of the company's push to incorporate artificial intelligence into education.
