1. An apparatus, comprisinga radio frequency identification (RFID) tag containing circuitry to:
- receive a first wireless command directed to the RFID tag from an RFID reader;
enter, resultant to said receiving receipt of the first wireless command, a non-responsive mode during which the circuitry is disconnected from an antenna and the RFID tag does not transmit responses to any RFID reader;
perform an internal action in response to a received signal when in the non-responsive mode; and
exit the non-responsive mode based on a timing circuit within the RFID tag.

Abstract
A radio frequency identification (RFID) tag may have a non-responsive mode, triggered by a command from an RFID reader, that temporarily prevents the RFID tag from responding to a query from any RFID reader for a period of time. In some embodiments this non-responsive mode may automatically end after a certain period of time without further action by the RFID reader. In other embodiments this non-responsive mode may end when directed to by another command addressed specifically to the RFID tag.

10. An apparatus, comprising
a radio frequency identification (RFID) tag, containing circuitry to: -
receive a particular wireless command directed to the RFID tag from a particular RFID reader; enter, resultant to said receiving receipt of the particular command, a non-responsive mode during which the circuitry is disconnected from an antenna and the RFID tag does not transmit responses to any RFID reader; perform an internal action in response to a received signal when in the non-responsive mode; and exit the non-responsive mode resultant to the particular RFID tag receiving a command addressed to the RFID tag directing the RFID tag to exit the non-responsive mode.

11. A method, comprising:
-
receiving a wireless command from a radio frequency identification (RFID) reader to enter a non-responsive mode of operation; entering the non-responsive mode resultant to receiving the command by disconnecting from an antenna; performing an internal action in response to a received signal when in the non-responsive mode; and returning to a responsive mode resultant to an internal event not based on any wireless command received while in the non-responsive mode. - View Dependent Claims (12, 13, 14)

15. A method, comprising:
-
receiving, by a radio frequency identification (RFID) tag, a first wireless command from an RFID reader to enter a non-responsive mode of operation; entering the non-responsive mode as a result of receiving the first wireless command by disconnecting from an antenna; performing an internal action in response to a received signal when in the non-responsive mode; receiving a second wireless command addressed to the RFID tag, the second wireless command directing the RFID tag to enter a responsive mode of operation; and exiting the non-responsive mode resultant to receiving the second wireless command.

16. An article comprising
a tangible machine-readable medium that contains instructions, which when executed by one or more processors result in performing operations comprising: -
causing transmission of an enabling signal to multiple radio frequency identification (RFID) tags; receiving a response from a particular RFID tag; and causing transmission of a first command addressed to the particular RFID tag to direct the particular RFID tag to enter a non-responsive mode by disconnecting from an antenna, the first command to include an indicator of an intended duration of the non-responsive mode. - View Dependent Claims (17)
