^RT

^RT

Read RFID Tag

Description This command tells the printer to read the current RFID tag data. The data can be sent back to the host via the ^HV command.

Note • It is recommended that you use the ^RF, ^RM, and ^RR commands rather than the ^RT command. The ^RT command is provided only for backward-compatibility with label formats that were developed for other Zebra RFID printers.
