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.
