At the Futian station, instead of presenting a ticket or scanning a QR bar code on their smartphones, commuters can scan their faces on a tablet-sized screen mounted on the entrance gate and have the fare automatically deducted from their linked accounts, says a news report.
The facial-recognition ticketing service is currently in trial mode, but it could help improve the efficiency of handling the up to 5 million rides per day on the city’s subway network, the report notes.
