I am setting up my RFID label with SGTID-96 protocol for Wal-Mart.  I am trying to use the RFID's label TID as part of the serialization.  I have went through and set up the driver command for TID, but when I input the code it tells me an invalid character is used.  If others have set up serialization without using TID, how did you do it?  I am new to all this.
