^RF — RFID Read and Write

Goal

Read and write RFID tags with ^RF.

Description

^RF reads or writes the tag: W writes, R reads, L writes with lock; data type A (ASCII), H (hex) or E (EPC — set up with ^RB first).

Example

^XA
^RB96,8,3,3,24,20,38
^RFW,E^FD48,0,5,6438092,0,12345^FS
^FO20,120^A0N,28,28^FDEPC written to tag^FS
^XZ

Result

The EPC block is written to the tag; preview services skip RFID, so the text line shows the label body.
