Abstract

A mobile communications device includes a near field communication (NFC) device, a movement determining device, and a processor coupled with the NFC device and the movement determining device. The processor performs operations for selectively switching between a first operating mode, in which the NFC device is enabled for NFC communication, and a second operating mode. When switched to the unsecure operating mode, the processor performs operations for enabling the NFC device for NFC communication until the mobile communications device moves beyond a threshold distance based upon the movement determining device.

First claim

That which is claimed is:

1. A mobile communications device comprising:
a memory that stores instructions;
a first near field communication (NFC) device;
a movement determining device; and
a processor coupled with the memory, the first NFC device, and the movement determining device, wherein the processor, responsive to executing the instructions, performs operations comprising:
initiating a first operating mode, wherein, during the first operating mode, the first NFC device is unconditionally enabled for NFC communication;
presenting a display menu for selecting a trigger event for disabling NFC communication in a second operating mode;
receiving a user selection of the triggering event via the display menu;
receiving a request to switch from the first operating mode to the second operating mode;
switching to the second operating mode responsive to the receiving of the request to switch, wherein the first NFC device is conditionally enabled for NFC communication during the second operating mode;
sensing, via the first NFC device, a second NFC device in near proximity during the second operating mode; and
responsive to the sensing of the second NFC device in near proximity during the second operating mode:
detecting the triggering event according to the movement determining device;
if the triggering event is not detected, transmitting a first NFC message to the second NFC device via the first NFC device to facilitate a first transaction; and
if the triggering event is detected, disabling further NFC communication during the second operating mode.

2. The mobile communications device of claim 1 wherein the detecting the triggering event is further according to detecting performance of excessive NFC transactions via the first NFC device.

3. The mobile communications device of claim 1 wherein the detecting the triggering event is further according to detecting expiration of a timer that is initiated responsive to the switching to the second operating mode.

4. The mobile communications device of claim 1 wherein the operations further comprise performing payment transactions via the first NFC device, and wherein the detecting the triggering event is further according to detecting performing excessive payment transactions via the first NFC device.

5. The mobile communications device of claim 1 , wherein the operations further comprise:
determining a first location associated with the switching to the second operating mode; and
tracking, via the movement determining device, movement relative to the first location, and wherein the detecting the triggering event is further according to detecting movement exceeding a movement limit.

6. The mobile communications device of claim 1 wherein the movement determining device comprises a wireless communications device, a satellite positioning system device, or any combination thereof.

7. The mobile communications device of claim 6 wherein the wireless communications device comprises a Bluetooth device, a wireless local area network (WLAN) device, or any combination thereof.

8. The mobile communications device of claim 1 wherein the movement determining device comprises an accelerometer.

9. The mobile communications device of claim 1 further comprising an input device coupled with the processor, and wherein the operations further comprise detecting an activation of the input device, wherein the activation is associated with the request to switch from the first operating mode to the second operating mode.

10. A communications system comprising:
a first near field communication (NFC) device; and
a mobile communications device comprising:
a memory that stores instructions;
a second NFC device; and
a processor coupled with the memory and the second NFC device, wherein the processor, responsive to executing the instructions, performs operations comprising:
presenting a display menu at the second NFC device for selecting a trigger event for disabling NFC communication in a second operating mode;
receiving a user selection of the triggering event via the display menu;
receiving a request to switch the second NFC device from a first operating mode, wherein the second NFC device is unconditionally enabled for NFC communication with the first NFC device in the first operating mode, to a second operating mode, wherein the second NFC device is conditionally enabled for NFC communication with the first NFC device in the second operating mode;
switching the second NFC device to the second operating mode responsive to the receiving of the request to switch operating modes;
sensing, via the second NFC device, the first NFC device in near proximity during the second operating mode; and
responsive to the sensing of the first NFC device in near proximity during the second operating mode:
detecting the triggering event according to a movement determining device;
if the triggering event is not detected, transmitting an NFC message to the first NFC device via the second NFC device to facilitate a transaction; and
if the triggering event is detected, disabling further NFC communication during the second operating mode.

11. The communications system of claim 10 wherein the detecting the triggering event is further according to detecting performance of excessive NFC transactions via the second NFC device.

12. The communications system of claim 10 wherein the detecting the triggering event is further according to detecting expiration of a timer that is initiated responsive to the switching to the second operating mode.

13. The communications system of claim 10 wherein the transaction comprises a payment transaction with the first NFC device via the second NFC device, and wherein the detecting the triggering event is further according to detecting performance of excessive payment transactions via the second NFC device.

14. A method, comprising:
presenting, by a processing system comprising a processor, a display menu for selecting a trigger event for disabling near field communication (NFC) in a second operating mode;
receiving, by the processing system, a user selection of the triggering event via the display menu;
detecting, by the processing system, a request to switch from a first operating mode, wherein a first NFC device is unconditionally enabled for NFC communication in the first operating mode, to the second operating mode, wherein the first NFC device is conditionally enabled for NFC communication in the second operating mode;
switching, by the processing system, to the second operating mode responsive to the detecting of the request to switch operating modest;
sensing, by the processing system, via the first NFC device, a second NFC device in near proximity during the second operating mode; and
responsive to the sensing of the second NFC device in near proximity during the second operating mode:
detecting, by the processing system, the triggering event according to a movement determining device;
if the triggering event is not detected, transmitting, by the processing system, an NFC message to the second NFC device via the first NFC device to facilitate a transaction; and
if the triggering event is detected, disabling, by the processing system, further NFC communication during the second operating mode.

15. The method of claim 14 wherein the detecting the triggering event is further according to detecting performance of excessive NFC transactions.

16. The method of claim 14 wherein the detecting the triggering event is further according to detecting expiration of a timer that is initiated responsive to the switching t
