Face scans for capital's metroWorld | AGENCE FRANCE-PRESSE 31 Oct 2019
Beijing will use facial recognition tools to speed up security checks in the city's overcrowded metro, using a "credit system'' to sort passengers into different channels.
Long queues and commuters arguing with staff over slow security procedures are common during rush hour in the metro system for 20 million people.
The city plans to install cameras that will scan the faces of passengers as they enter a subway station and sort them into different security channels, said Zhan Minghui, director of the Beijing Rail Traffic Control Center.
He said the plan involves creating a "passenger credit system," and individuals on a "white list" will be offered expedited security clearance, Beijing Youth Daily reported.
Those who receive "abnormal feedback" after their faces are scanned will be subjected to extra checks.
Zhan did not offer details on the criteria used to sort passengers or what could trigger that type of feedback.
"The technique aims to improve the efficiency of security checks and includes both body checks and luggage screening when large numbers of passengers enter the station," he told a transport forum.
Zhan did not give a timetable for the technology.
The Beijing subway in May said it has started "deducting credit points" from passengers who eat in railway carriages.
