1. A radio frequency identification device (RFID) tag comprising:
- a processor;
a transceiver coupled to the processor, the RFID tag being configured to respond to commands issued by a reader and received by the transceiver; and
read-only memory coupled to the processor, the read-only memory containing a kill password that cannot be changed, the kill password being set at a value selected such that it is not possible for a reader to kill a RFID tag by sending a kill command.
