1. A portable device comprising:
- a radio frequency identification device having an active and a passive mode, wherein, when operating in the active mode, the radio frequency identification device is configured to respond to an external query by at least generating a radio frequency signal including a predetermined code, and wherein, when operating in the passive mode, the radio frequency identification device is configured to not respond to the external query;
a geographic locator configured to generate a geographic location signal indicative of a current geographic location of the portable device; and
a controller configured to determine, based on the geographic location signal, the current location of the portable device, in response to determining that the current geographic location of the portable device is near a predetermined geographic location, set the radio frequency identification device to the active mode, and, in response to determining that the current geographic location of the portable device is not near the predetermined location, setting the radio frequency identification device to the passive mode.

Abstract
A composite device includes an RFID device and a controller. The controller allows the RFID to respond to a query from an external source only when the composite device is at a predetermined location. In this manner, a code associated with the RFID is not released by the RFID anywhere in the world except at the location of the query requester.

5. A method comprising:
-
determining, by a portable device, a current location of the portable device; determining, by the portable device, whether the current location of the portable device is near a predetermined geographic location; responsive to determining that the current location of the portable device is near a predetermined geographic location, setting, by the portable device, a radio frequency identification device of the portable device to an active mode, wherein the radio frequency identification device of the portable device responds to an external query while operating in the active mode; and responsive to determining that the current location of the portable device is not near a predetermined geographic location, setting, by the portable device, the radio frequency identification device of the portable device to a passive mode, wherein the radio frequency identification device of the portable device does not respond to the external query while operating in the passive mode; receiving, by the portable device, the external query; if the radio frequency identification device is operating in the active mode, responding to the external query by at least generating a radio frequency signal including a predetermined code; and if the radio frequency identification device is operating in the passive mode, refraining from responding to the external query. - View Dependent Claims (6, 7, 8)

9. A non-transitory computer-readable memory encoded with instructions that, when executed by a processor of a portable device, cause the processor to:
-
determine a current location of the portable device; determine whether the current location of the portable device is near a predetermined geographic location; responsive to determining that the current location of the portable device is near a predetermined geographic location, set a radio frequency identification device of the portable device to an active mode, wherein the radio frequency identification device of the portable device responds to an external query while operating in the active mode; and responsive to determining that the current location of the portable device is not near a predetermined geographic location, set the radio frequency identification device of the portable device to a passive mode, wherein the radio frequency identification device of the portable device does not respond to the external query while operating in the passive mode; receive the external query; if the radio frequency identification device is operating in the active mode, respond to the external query by at least generating a radio frequency signal including a predetermined code; and if the radio frequency identification device is operating in the passive mode, refrain from responding to the external query. - View Dependent Claims (10, 11, 12)
