The Fareclock REST API, returning data in JSON, available on its pro service only, allows you to integrate this time clock into other applications. We previously wrote about the implications of how crowded the face recognition space is with 38 APIs in our directory, suggesting among other things that it isn't clear how so many companies offering the technology will maintain an edge and survive. But Fareclock represents a different breed of business design: use facial recognition to create an app, in this case a time clock that employees can punch, that in turn can be used via an API.
