If yes please, what is the wrong in my code below, what additional things needed more than the host ip and port number to connect with Device? Is a Socket can consider as a solution for such problem? Is there any general, standard way to connect, send and retrieve data from such device using Java? Currently, I tried to connect with the device by creating a Socket Object (through Ethernet port) but also not executed with me! This open infinity loop problems on my head! I research for a global standard on how to connect, send and retrieve data with a Fingerprint Device which again I wasn't lucky enough to find a clear solution. However, I am search and reading about that and I see the SDK could used which based on device type (which hard, not logical, moreover, it is not global solution!) The device I am using is a Biocom Fingerprint attendance system. I am trying to connect with a Biometric Fingerprint Attendance Device using a Java Program (actually I am newbie in that!).
