The Beijing subway system plans to introduce bio-recognition technology this year to reduce heavy passenger flow that sometimes lead to kilometers of long lines outside of busy stations, according to China Daily.
A senior manager at Beijing subway told China Daily that two bio-recognition technologies including facial recognition and palm touch are considered.
Facial recognition technology can track passenger movements with cameras connected to online networks that recognize passengers who enter the station. The technology potentially allows passengers to bypass traditional ticketing. But how passengers will pay for tickets remains an unsolved issue.
Starting in April, passengers in Beijing subway was able to use mobile QR codes in mobile payment platforms including WeChat Pay and Alipay, rather than queuing to buy tickets. The usage of one-way ticket reduced about 20% to 600,000 from 800,000 after the introduction of QR codes, therefore helping to reduce lines at ticketing stations.
In Shanghai, passengers can swipe their hands to enter the stations. The hand images can be compared with records in the subway system’s database within seconds.
Facial recognition is widely applied in public service in China. Police in Shenzhen installed AI cameras to identify and single out jaywalkers. Also, patrol officers in the city of Zhengzhou used facial recognition sunglasses to spot criminal suspects during the busy Chinese New Year travel season.
