The disclosed embodiments of the present invention are used to permanently
disable or destruct an RFID so that it is no longer possible to read some
or all of the data encoded on the RFID tag. In one method for disabling
data on a radio frequency identification (RFID) tag, an RFID tag is
identified and its identity is confirmed. Verification that a
prerequisite event has occurred is obtained, occurrence of which is
required prior to disablement of the data. A destruct instruction is
transmitted to the RFID tag. The RFID tag verifies that the destruct
instruction is valid and disables the data upon verifying validity of the
destruct instruction. The tag may disable the data by erasing the data,
disabling the data, auto-destructing, or performing any operation that
makes the data unreadable.
