Abstract

A near field communications (NFC) device is disclosed that interacts with other NFC devices to exchange information and/or the data. The NFC device can include a plurality of secure elements each configured to store one or more card emulation instances. Each card emulation instance is associated with an application identification (AID) and a priority value. The NFC device can route communications between another NFC device and plurality of secure elements based on each card emulation instance's associated AID and priority value.

First claim

What is claimed is:

1. A Near Field Communication (NFC) device, comprising:
a plurality of secure elements configured to store a plurality of card emulation instances, each of the plurality of card emulation instances being associated with a corresponding application identification (AID) from among a plurality of AIDs and a corresponding priority value from among a plurality of priority values, at least one AID from among the plurality of AIDs being associated with the plurality of card emulation instances, the plurality of card emulation instances being stored by more than one of the plurality of secure elements; and
an NFC module configured to:
select a card emulation instance from among the plurality of card emulation instances that is associated with AID information that is received from a second NFC device, the AID information identifying an AID from among the plurality of AIDs,
wherein the NFC module is configured to select the card emulation instance having a highest priority value from among the plurality of priority values when the plurality of card emulation instances is associated with the identified AID, and
route wireless communications between the second NFC device and a secure element from among the plurality of secure elements that is associated with the selected card emulation instance to establish access to the selected card emulation instance.

2. The NFC device of claim 1 , wherein the NFC module is further configured to select the card emulation instance having a next highest priority value from among the plurality of priority values when the card emulation instance having the highest priority value is unavailable.

3. The NFC device of claim 1 , wherein the corresponding priority value for each of the plurality of card emulation instances is set by a user prior to establishing wireless communication with the second NFC device.

4. The NFC device of claim 1 , wherein the corresponding priority value for each of the plurality of card emulation instances is set by a user following receipt of the AID information from the second NFC device.

5. The NFC device of claim 1 , wherein the NFC module comprises:
a memory that stores a plurality of look-up-tables (LUTs) having the plurality of AIDs, the plurality of priority values, and secure element information indicative of corresponding secure elements from among the plurality of secure elements in which the plurality of AIDs is stored, each LUT from among the plurality of LUTs corresponding to a different AID from among the plurality of AIDs, and
wherein the NFC module is configured to select the card emulation instance using a LUT from among the plurality of LUTs that is associated with the identified AID.

6. The NFC device of claim 1 , wherein the plurality of card emulation instances comprises:
monetary transaction information;
electronic ticketing information;
security clearance information; or
personal identification information.

7. The NFC device of claim 1 , wherein the NFC module comprises:
an antenna module, including an indicative coupling element, configured to generate a recovered communication signal from a received communication signal inductively coupled onto the inductive coupling element from the second NFC device; and
a controller module configured to receive the recovered communication signal and to route the recovered communication signal to the secure element.

8. The NFC device of claim 7 , wherein the controller module is configured to examine a packet of the recovered communication signal to determine the identified AID.

9. A method of routing wireless communications between a plurality of secure elements of a Near Field Communication (NFC) device and a second NFC device, the plurality of secure elements being configured to store a plurality of card emulation instances, the method comprising:
assigning a priority value from among a plurality of priority values to each of the plurality of card emulation instances stored in the plurality of secure elements;
receiving application identification (AID) information from the second NFC device;
selecting an AID from among a plurality of AIDs based on the AID information, at least one AID from among the plurality of AIDs being associated with the plurality of card emulation instances, the plurality of card emulation instances being stored by more than one of the plurality of secure elements;
selecting a card emulation instance from among the plurality of card emulation instances that is associated with the selected AID, the card emulation instance having a highest priority value from among the plurality of priority values being selected when the plurality of card emulation instances is associated with the selected AID; and
routing the wireless communications between a secure element from among the plurality of secure elements that is associated with the selected card emulation instance and the second NFC device.

10. The method of claim 9 , wherein the selecting the card emulation instance comprises:
determining which of the plurality of secure elements currently store the plurality of card emulation instances that is associated with the selected AID; and
determining which secure element from among the determined plurality of secure element currently stores a card emulation instance that is associated with the selected AID having the highest priority value.

11. The method of claim 10 , wherein the selecting the card emulation instance further comprises:
determining another card emulation instance from among the plurality of card emulation instances that is associated with the selected AID that has a next highest priority value from among the plurality of priority values when the card emulation instance having the highest priority value is unavailable.

12. The method of claim 9 , wherein the assigning the priority values is performed prior to the receiving the AID information.

13. The method of claim 9 , wherein the assigning the priority values is performed after the receiving the AID information.

14. The method of claim 9 , wherein the selecting the card emulation instance comprises:
selecting the card emulation instance from a plurality of look-up-tables (LUTs) corresponding to the selected AID, the plurality of LUTs including the plurality of AIDs, the plurality of priority values and secure element information indicative of corresponding secure elements from among the plurality of secure elements in which the plurality of AIDs is stored, each LUT from among the plurality of LUTs corresponding to a different AID from among the plurality of AIDs.

15. The method of claim 9 , wherein the assigning the priority values comprises:
automatically assigning the card emulation instance the highest priority value if the card emulation instance is the only card emulation instance associated with the selected AID.

16. The method of claim 9 , wherein the AID information comprises:
a list of one or more AIDs associated with each of the plurality of card emulation instances.

17. A Near Field Communication (NFC) device, comprising:
a plurality of secure elements, each secure element from among the plurality of secure elements storing a card emulation instance associated with a first application identification (AID) from among a plurality of card emulation instances and a priority value from among a plurality of priority values, at least one AID from among the plurality of AIDs being associated with the plurality of card emulation instances, the plurality of card emulation instances being stored by more than one of the plurality of secure e
