I have a Zebra FX9600 RFID reader. I am trying to read RFIDS using the java SDK provided by Zebra technologies. The SDK works fine but the only issue the range(few inches) in which the reader is able to read tags. The tags need to be very close to the antenna in order for the reader to pick it up. This will not work in production as we need to pick RFID tags in a large space. How can I solve this issue?
