O p t i o n 6 3 ( L o c k Ta g )
Use this option to prevent the data in the RFID tag from being
reprogrammed. It is similar to the write-protect feature on
diskettes. This is also referred to as locking a tag.
Not all protocols support Option 63 (Lock
Tag). Additionally, you cannot lock 64-bits of
data into a 96-bit tag.
Syntax R,63,code p
R1. R Option Header.
R2. 63 Option 63.
R3. code One ASCII character in the 0-255 range. This character must
be used to "kill" an RFID tag and must match the tag being
killed. Keep track of this code, because when an RFID tag is
killed, this code must match the code already "locked" in the
RFID tag.
Example X,5,16,0 p
R,63,250 p
Prevents the RFID tag from being reprogrammed and sets the
lock/kill code to 250.
Example X,5,16,0 p
R,63,75 p
