STX KtU  Read Unique Serial Number from RFID Tag  
 
(Direct Mode – HF [13.56 MHz] ISO15693 Tag Interface) 
 
This command instructs the RFID device to read the unique serial number data from the 
tag and then place that data into a replaceable field. It is expected that the tag 
transponder will be within the read / write distance of the RFID programming device; 
otherwise, “Void” will be printed in the text or bar code label field(s).   
 
 
This is a sixteen character alphanumeric value; the replaceable field must have an 
adequate length.
