Face recognition machines have been added so passengers can quickly pass through railway stations in many cities, such as Beijing, Shanghai, Guangzhou, Zhengzhou, Taiyuan, Wuhan, Nanchang, Xi'an and Changsha.
These machines allow passengers to check their tickets by themselves while passing the safety-check gates, which takes each person only three to six seconds.
