The main railway station in China's capital, Beijing, has started trialling facial recognition technology to verify the identity of train travellers.Citizens who hold a second-generation identification card and a blue magcard ticket can use the new automated check-in, reportsThey must stand in front of a screen to have their picture taken and then wait for approximately three seconds for it to be verified.Introduced in 2004, China's second-generation ID card contains a chip which contains a digital photograph along with essential personal information of the holder.Facial recognition is increasingly being proposed as a possible banking solution in China, with its Tencent-backed internet bank planning to use the tech to identify new account holders.
