SHANGHAI - The Chinese capital, Beijing, is looking at introducing "bio-recognition technology", including palm scanners and facial recognition cameras, to speed up passenger flow through subway stations at peak times, state media reported on Tuesday.
China is increasingly using surveillance technology for everything from bolstering domestic security to speeding up orders at fast-food restaurants. However, that kind of monitoring is stoking concerns from human rights groups that it is building a nationwide surveillance system to quell dissent.
Beijing's sprawling underground transport system plans to introduce the technologies this year, the state-run China Daily newspaper said, citing Zhang Huabing, head of enterprise development for the main operator, Beijing Subway.
The facial recognition cameras would be able to detect people's faces, potentially allowing them to bypass normal ticketing channels, while the palm scanners would enable some people to swipe their hands to get through ticket turnstiles.
The China Daily said palm scanners were already being used on the Shanghai subway system, which compared scanned images with a database of prints in seconds.
It said Beijing has 22 urban railway lines and that more than 10 million passengers ride the city's subway trains on an average working day.
