Traditionally, we take the subway with our subway cards or by scanning（扫描）QR codes on our smartphones. But now, when people travel on the Beijing Daxing Airport Express subway, they will have a new way to take a ride — they can scan their palms（手掌）.
To enjoy the service, people need to register（登记）their palm prints on machines in subway stations along the Daxing Airport Express subway line. Then they have to activate（激活）the palm-scanning function on their smartphones. Once they do this, they can scan their palms at ticket gates to pass through. After they finish the travel, the payment service on their smartphones will pay the money for their ride.
Many people welcome the new technology. They think it helps them to travel faster and more easily. They don't have to take out their subway cards or smartphones when they want to pass through ticket gates. And they no longer have to worry when they forget their subway cards or when their smartphones run out of battery（没电）. What's more, the palm-scanning technology is very friendly to old people and people with special needs. This technology makes it possible for them to take the subway without using smartphones.
Besides Beijing, the palm-scanning technology is also in service in the subway station of Shenzhen. And there are hopes that people can use it in more places like stores and restaurants in the future.
