Abstract
Techniques that enable a device to advertise its mode of operation using an RFID tag attached to the device. Techniques are provided for programmatically controlling an RFID tag. An RFID tag attached to a device is programmatically enabled or disabled depending upon the mode(s) of operation of the device. The RFID tag is able to transmit a signal when enabled and not able to transmit a signal when disabled. Using such a controllable RFID tag, a device can efficiently indicate or advertise its mode of operation to an RFID reader or sensor.

2. A method, comprising:
-
determining a change in an operating mode of a device from a first mode to a second mode; and upon determining the change, changing a state of an antenna of a radio frequency identification (RFID) tag associated with the device from a first state to a second state; wherein the RFID tag is enabled to receive an interrogation signal from an RFID reader when the antenna is in the first state; and wherein the RFID tag is disabled when the antenna is in the second state. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9)
