In something straight out of science fiction, the high tech city of Shenzhen, a local subway operator is testing facial recognition subway access, powered by a 5G network.

From the article:

The trial is limited to a single station thus far, and it’s not immediately clear how this will work for twins or lookalikes. People entering the station can scan their faces on the screen where they would normally have tapped their phones or subway cards. Their fare then gets automatically deducted from their linked accounts. They will need to have registered their facial data beforehand and linked a payment method to their subway account.
