RFID PERMALOCK - RFID Permanent Lock

RFIDUnsupported

Plain English

⚠️ **Irreversibly locks `<bank>` — the bank cannot be unlocked again.** Convenience wrapper for `RFID LOCK "<bank>", "<password>", 3` (Gen2 policy 3 = permanently-locked). `<password>` is the 8-hex-character (32-bit) access password. After successful execution, the bank's lock state cannot be changed — subsequent `RFID LOCK` or `RFID PERMALOCK` calls against that bank will fail.

When to use

Supply-chain workflows where the EPC must never be rewritten after the tag leaves the encoding station. Use sparingly — once permalocked, you cannot recover the bank for re-use.

Syntax

RFID PERMALOCK "<bank>", "<password>"
