Following the QR code and facial recognition, Beijing Subway and WeChat Pay have recently started deploying a palm print recognition system on the Daxing International Airport Line, which allows passengers to take the subway train by scanning the palms of their hands.

Palm print scanners were installed on the ticket machines and at ticket gates at stops along the Daxing International Airport Line. Passengers can access the subway trains of the line after scanning and uploading their palm print at the ticket machine, then link it to their personal phone number and ID via WeChat mini program.

Palm print recognition system can help passengers access the subway in case their mobile phone runs out of battery or in case they don't carry any cash on them. The payment will be completed after the passengers finish their trip.
