Beijing subways to get bio-ID system

The Beijing subway system plans to introduce bio-recognition technology at stations this year to improve transport efficiency and reduce costs, a senior manager said last week.

Two bio-recognition technologies - facial recognition and palm touch - are being considered, said Zhang Huabing, head of enterprise development for Beijing Subway, the operator of most lines in the city, during the International Metro Transit Exhibition in Beijing on Thursday.

Facial recognition technology can track passenger movements with cameras connected to online networks that recognize people when they enter a station, potentially allowing them to bypass traditional ticketing.
