I'm involved in doing a project RFID based asset tracking, unfortunately i got stuck with retrieving data into our java program from the rfid reader connected to the system using an usb port. I need some help in writing a java code regarding how to access the data from usb.

Actually, the RFID reader catches the data from the tag(tag id) and this tag id need to be accessed into our java program.

can any one help me regarding this issue.
