RFWTAG
Purpose
The RFWTAG command is used to program an RFID
tag (embedded in a smart label) using structured data
format. The data structure of an RFID tag can consist
of one or more bit fields. Each bit field specifies its own
field length, the data format, the field type plus
additional options if the type is incremental, and finally
the field value.

LOCK
n[;format]
Optional parameter to lock the data block
to prevent it from being overwritten. By
default, the data are not locked initially. n is
the passcode. The acceptable values for n
are 1 to FFFFFFFF in hex, a 4 bytes data.
When the LOCKn option is used to lock
any memory bank, which at the same time
is programmed with the write data, the
same passcode will be written on ACS
memory bank. The ACS memory bank will
also be locked if ACS is not locked at the
time of the operation. If ACS is already
locked at the time of the operation, the
passcode needs to match the current
content of ACS so that the memory bank
lock takes effect. The passcode (n) can
also be in dynamic format. For dynamic
format, enter LOCK<DFn>, where DFn is
to prevent it from being overwritten. By
default, the data are not locked initially. n is
the passcode. The acceptable values for n
are 1 to FFFFFFFF in hex, a 4 bytes data.
