Techniques that enable a device (104) to advertise its mode of operation using an RFID tag (106, 400) 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 (102) or sensor. |
