Abstract

In accordance with an example embodiment of the present invention, mobile device comprises a battery, a short-range wireless communication (SRW) chip set, a secure element incorporated into the battery, and a bootloader, wherein the SRW chip set is configured to sense proximity to a point of sales terminal and, in response, initiate bootup of the mobile device, and wherein the bootloader is configured to determine that bootup was initiated by the SRW chip set and, in response, power up only the SRW chip set and the secure element.

Claims

1. An mobile device, comprising:

a battery;

a short-range wireless (SRW) communication chip set;

a secure element incorporated into the battery; and

wherein the SRW chip set is configured to sense proximity to a point of sales terminal and, in response, initiate bootup of the mobile device, and power up only the SRW chip set and the secure element.

2. The mobile device of claim 1, further comprising a power management module configured to monitor reserve battery power, wherein the power management module is configured to disable power to the mobile device and only provide power to the SRW chip set and the secure element when the reserve battery power drops below a minimum threshold.

3. The mobile device of claim 1, wherein the SRW chip set is incorporated into the battery.

4. The mobile device of claim 2, wherein the power management module is incorporated into the battery.

5. The mobile device of claim 1, further comprising an activation switch which is configured for disconnecting the secure element.

6. The mobile device of claim 1, further comprising a display configured to indicate whether the SRW chip set is connected.

7. The mobile device of claim 1, further comprising an antenna incorporated into the battery and connected to the SRW chip set.

8. The mobile device of claim 1, wherein the SRW chip set further comprises a power radio and a data radio.

9. The mobile device of claim 8, wherein the secure element is configured to switch between the power radio and data radio based on predetermined criteria.

10. The mobile device of claim 1, further comprising a bootloader configured to determine bootup was initiated by the SRW chip set and, in response, indicated that only the SRW chip set and secure element should be booted up.

11. A method, comprising:

sensing proximity to a point of sales terminal;

initiating bootup of a mobile device in response to sensing proximity to the point of sales terminal; and

powering up only Trusted Execution Environment (TrEE) elements in the mobile device.

12. The method of claim 11, wherein a short-range wireless communication (SRW) chip set initiates bootup of the mobile device in response to sensing proximity to the point of sales terminal.

13. The method of claim 11, wherein the TrEE elements comprise a short-range wireless communication chip set and a secure element.

14. The method of claim 11, wherein the TrEE elements negotiate a transaction with the point of sales terminal.

15. The method of claim 11, wherein the SRW chip set initiates bootup in response to sensing proximity to the point of sales terminal and wherein a bootloader determines that bootup was initiated by the SRW chip set and, in response, powers up only the TrEE elements.

16. The method of claim 11, further comprising:

monitoring reserve battery power; and

disabling power to the mobile device and only providing power to the TrEE elements when the reserve battery power drops below a minimum threshold.

19. The method of claim 16, wherein the TrEE element comprise a secure element incorporated into a battery in the mobile device and a short-range wireless communication (SRW) chip set.

17. A method comprising:

monitoring reserve battery power in a mobile device having Trusted Execution Environment (TrEE) elements configured for executing secure transactions;

disabling power to the mobile device and only providing power to the TrEE elements when the reserve battery power drops below a minimum threshold.

18. The method of claim 17, further comprising:

sensing proximity to a point of sales terminal;

initiating bootup of a mobile device in response to sensing proximity to the point of sales terminal; and

powering up only TrEE elements in the mobile device.

20. The method of claim 18, wherein the TrEE elements negotiate a transaction with the point of sales terminal.
