The city of Guangzhou, Guangdong province, has installed a face identification security system at three of its underground metro stations.

The face identification security system allows people with no handbags or luggage to quickly go through security, improving the efficiency of the process. In the future, it could be possible that passengers will be able to pay the metro fee with face identification.  

The face identification security system incorporates a door with sensors and a glass shield. To the side of the door is a camera and a QR barcode area, which is where the face identification process occurs. AI technology is incorporated in the system, so no security guards are needed. 

The face identification security system is designed for speed and accuracy, aiming to lessen the time and energy it takes for people to get to work. Through the internet, big data, QR code scanning, AI technology and other innovative designs, the face identification security system should greatly improve the metro experience once pushed out to the rest of China.

Statistics show that in 2017 the Guangzhou metro system saw 2.8 billion people. On average, 7.7 million people rode the metro each day; the highest recorded number of people riding the metro in a day was 10 million people. Efficiency is very important for transportation systems, and the face identification security system may change transportation for the better.
