TimeTrex Time and Attendance

I want to develop a desktop application that will perform the punching action. I have had a look at all the scripts that are resposible for punching and none of them give me an understanding of how they can be used by an external application. What values need to be passed to which script?

Any help would be greatly appreciated.

Such an application already exists, its called the TimeTrex Desktop Quick Punch application and its available with our Business or Professional Editions, it also supports different hardware devices that we offer at our Online Store and offline mode too.
