Programmatic control of RFID tags
First Claim
1. A method of controlling a radio frequency identification (RFID) tag associated with a device, the device being capable of operating in at least a first mode and a second mode, the method comprising:
- upon a change in operating mode of the device from the first mode to the second mode, receiving, at a controller apparatus coupled to the RFID tag, a first indication that the device is operating in the second mode;
enabling, by the controller apparatus, based on the first indication, transmission of signals by the RFID tag, wherein the RFID tag is a passive RFID tag, andwherein the enabling comprises unclamping two poles of an antenna of the RFID tag.

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.

10. A system comprising:
-
a device configured to operate in a first mode and a second mode different from the first mode; a passive radio frequency identification (RFID) tag coupled to the device; and a controller apparatus coupled to the RFID tag; wherein the controller apparatus is configured to; upon a change in operating mode of the device from the first mode to the second mode, receive a first indication that the device is operating in the second mode; and enable, based on the first indication, transmission of signals by the RFID tag by unclamping two poles of an antenna of the RFID tag. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 21, 22)
