Connect to remote device.

Question

Hi ,

I'm doing a time and attendance project using a biometric reader(finger print) in asp.net with c#. If i want my softwate to communicate with the reader , i use the following code ,
bIsConnected = CtrlBioComm.Connect_Net("192.168.1.12", 4370);
where 192.168.1.12 is the ip of the reader.
But now i want to communicate with the remote reader. I have a static Ip.. Is it possible?.. Someone told me i have to use web service to achieve this.. Can anyone pls guide me..
