RFID LOCK (RFID Lock Bank) - TSPL Command Reference

Plain English

Applies a Gen2 access-policy lock to `<bank>` using the 32-bit access password (TSPL2 PG §RFID LOCK p116). `<password>` is 8 hex characters. `<policy>` is the Gen2 lock-action enum (0–3). Policy 3 is irreversible (use `RFID PERMALOCK` as the convenience wrapper). Note: the RESERVED bank exposes two named partitions on some firmware — `"KILL"` for the kill-password area and `"ACCESS"` for the access-password area.

When to use

After encoding the EPC (or other bank), to prevent unauthorised re-writes. Pair with `RFID WRITE`.

Syntax

RFID LOCK "<bank>", "<password>", <policy>
