A specific check-in service was launched on Sunday that allows passengers to ride subway trains after taking a quick hand scanning in a designated line of the Beijing Metro.
Passengers can use the palm-scanning service to check in at the Daxing Airport Metro Line.
Passengers need to enter their palm prints on registration machines installed at subway stations along the Daxing Airport Metro Line in southern Beijing and activate the "palm-scanning" function on the WeChat Mini-Program.
They can put their palms above the relevant palm-scanning machines when riding subway trains. They will scan their palms automatically and open the gate if their palm print has already been registered. The whole process takes only a few seconds.
The pilot of the palm-scanning service at the Daxing Airport Metro Line is also the first application of palm print recognition in the rail transit scene, which will provide more convenience for travelers around the country.
