Hunter's comment
Face++ technology is used by Chinas "Pay with you Face" system, the platform offers different technologies other than Face Recognition, they also offer Face Detection, Face comparing, Face landmarks, Face searching, Face Attributes, Emotion Recognition and many more. Face++ is a powerful platform they managed to perfectly create a Face Recognition system. The platform is free of charge if you signup but they have also the option of paying some feature in order to use some of it. They have the APIs and SDKs in order for us to use the service they offer.
