RFID READ (RFID Read Bank) - TSPL Command Reference

Plain English

Reads `<length>` bytes from `<bank>` starting at byte `<offset>` (TSPL2 PG §RFID READ p113). Offset and length are byte counts, not word counts. The read result is returned to the host as a hex string over the back-channel and may be displayed on the printer LCD on firmware that supports it. Engine-recognised but no SVG output — RFID operations don't produce label content.

When to use

For host-driven inventory audits, read-back-after-write verification, or to pull TID data for tag-authentication workflows. Pair with the printer's back-channel reader on the host side.

Syntax

RFID READ "<bank>", <offset>, <length>

Parameters

Parameter	Description
`bank`	Quoted Gen2 memory bank. `"EPC"` - Electronic Product Code bank (typically 12 bytes for SGTIN-96) `"USER"` - User memory bank (size varies by tag chip) `"TID"` - Tag Identifier bank (read-only, factory-programmed) `"RESERVED"` - Reserved bank (kill + access passwords, 8 bytes total)
`offset`	Byte offset within the bank (0-based).
