As that Ke P, mayor of Taipei, seemed awed by the highly-advanced electronical paying system he himself experinced in Shanghai, now China's Mainland already rendered to passengers a more streamlined service applicable at airports, railway stations, and subways: check in by your face.  You may say the service is not unusual because Taoyuan Airport has had similar service adopted in passport check.  But the service at Taoyuan Airport doesn't involve more complicated links such as reservation, payment, and so on.       

I guess from now on in Mainland "人可貌相"矣.
