The service allows passengers to take the subway with a quick scan of their hands. The passenger can activate the palm-scanning riding service with instructions on the ticket machine and mobile payment app. When taking the subway, passengers need to find the palm-scanning gate with a recognition area, scan the palm and pass through the gate. After exiting the station, the passenger will receive a deduction reminder push from the mobile payment app. The palm-scanning riding service now only allows one passenger to bind one palm-print information, and only supports the Chinese mainland residents over the age of 14 to activate.
