Beijing's subway deployed a palm print recognition system on its Daxing Airport Express on May 21, allowing passengers to take the subway by simply scanning their palms. This system mainly recognizes the palm print and veins of passengers. Passenger information is kept secure by using data desensitization and data encryption technology. It is the first subway line that supports palm print recognition in the world.
