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.

Claims

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.

2. The portable device of claim 1, wherein the controller is further configured to set the radio frequency identification device to the active mode in response to determining that the current geographic location is near a location of a source of the external query.

3. The portable device of claim 1, further comprising:

a memory configured to store the predetermined code.

4. The portable device of claim 1, further comprising:

a housing including the radio frequency identification device and the controller,

wherein the controller is configured to enable the radio frequency identification device to respond to the query with the predetermined code only if the current geographic location of the portable device matches a facility location, wherein the predetermined code provides access to the facility location.

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.

6. The method of claim 5, further comprising:

determining, by the portable device, whether the current location of the portable device is near a source of the external query,

wherein setting the radio frequency identification device of the portable device to the active mode is further in response to determining that the current location of the portable device is near the source of the external query.

7. The method of claim 5, wherein responding to the external query further comprises retrieving, by the portable device and from a memory of the portable device, the predetermined code.

8. The method of claim 5,

wherein the predetermined location is a facility location,

wherein determining whether the current location of the portable device is near the predetermined location includes determining whether the current location of the portable device is near the facility location, and

wherein the predetermined code provides access to a facility at the facility location.

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.

10. The non-transitory computer-readable memory of claim 9, further encoded with instructions to cause the processor to:

determine whether the current location of the portable device is near a source of the external query,

wherein the instructions further cause the processor to set the radio frequency identification device of the portable device to the active mode in response to determining that the current location of the portable device is near the source of the external query.

11. The non-transitory computer-readable memory of claim 9, further encoded with instructions to cause the processor to:

respond to the external query by at least retrieving, from a memory of the portable device, the predetermined code.

12. The non-transitory computer-readable memory of claim 9,

wherein the predetermined location is a facility location,

wherein determining whether the current location of the portable device is near the predetermined location includes determining whether the current location of the portable device is near the facility location, and

wherein the predetermined code provides access to a facility at the facility location.
