Honour of Kings uses facial recognition to check ages

One of China's most popular video games is testing the use of facial recognition to check users' ages. Honour of King's publisher Tencent announced the move at the weekend. It said the trial would initially be limited to "thousands" of new players based in Beijing and Shenzhen. The title has been criticised in local media over claims children have become addicted to it. But one expert questioned whether the test could be scaled up.
