#RFL – Write protect (Lock) and unprotect (Unlock) memory areas


Definition

Activate or disable the write protection (simple lock) of various memory areas of EPC Gen
2 tags. Before changing the write protection status first the access password must have
once been written into to access password memory of the tag with a write command
(#RFW or #SRF + #VW/T). For any attempt to change to protection status the same
password must be provided as part of the #RFL command.
Please note: the #RFL command itself doesn’t write to access password into to tag!
The #RFL command doesn’t support the permalock option specified in the EPC Gen 2
