STX KtR Read Data from RFID Tag
This command instructs the RFID device to read data from the tag and then put 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).

there are two digits per hex value, replaceable fields should be
twice as long than if using ASCII data (e.g., the character "A"
would be returned as "41").
