Pay with your face in this Chinese subway station

Whether you’re in New York or Beijing, getting into the subway usually requires reaching into your pocket to pull out a fare card or a smartphone. But in one Chinese city, train riders can now keep their hands idle.

In the eastern city of Jinan, the city’s subway operator has introduced facial recognition to one of its lines. After a passenger registers their face and payment details using the Jinan Metro App, they can enter the station just by looking into a screen at the turnstile, according to Chinese media.

Similar to Apple’s Face ID, the subway sensor casts thousands of infrared dots on a person’s face to create a 3D map. The process reportedly takes just two seconds, which subway officials say is faster than scanning a QR code, China’s preferred method of mobile payments.

This still isn’t fast enough for some people, though. In one Weibo comment with more than 3,000 likes, a user said, “Sorry, it only takes one second for me to swipe my transit card.”
