Abstract

In some embodiments, a system includes a mobile communication device and a secure element physically coupled to the mobile communication device. The mobile communication device includes a first wireless transceiver, first processor, first memory, first speaker, first microphone, and first Audio To Digital conversion (ADC). The secure element includes a second wireless transceiver, second processor, second memory, second speaker, second microphone, a second Audio To Digital converter (ADC), and a second Digital to Audio converter (DAC). The mobile communication device is configured to transmit data via the first speaker to the secure element microphone using inaudible sound waves. The secure element is configured to transmit data wirelessly via the second speaker to the mobile communication device using inaudible sound waves.

Claims

1. A system, comprising a secure element physically coupled to a watch:

a secure element wireless transceiver that transmits data to a point of sale terminal using inaudible sound waves, the secure element including a processor, memory, microphone, speaker, and an audio to digital converter and further wherein the

secure element wireless transceiver receives t data from the point of sale terminal.

2. The system of claim 1, wherein the data between the secure element and the point of sale terminal is transferred using inaudible analog sound waves encoded using sigma delta and transmitted at 10 Mhz or less such that the sound is inaudible to the human ear.

3. The system of claim 1 where the secure element transmits inaudible sound waves wirelessly using the speaker.

4. The system of claim 3, wherein the sound wave is diffracted or bent when the sound waves travel through the opening of the speaker in the secure element.

5. The system of claim 1, wherein the secure element is configured to use power received from the point of sale terminal to transmit data to the point of sale terminal during a near field communication induction.

6. The system of claim 1, wherein the secure element uses power from a power harvesting circuitry to harvest power from ambient RF signals.

7. The system of claim 1 where the secure element is powered by an internal battery

8. The system of claim 7, wherein the internal battery in the secure element is woken up and exits sleep mode after induction which occurs when the secure element is held in proximity to a POS/POE and an API in the secure element turns the second microphone on.

9. The system of claim 1, wherein the secure element includes a screen for displaying images.

11. The method of claim 1, wherein the data is transferred using inaudible analog sound waves encoded using sigma delta and transmitted at 10 Mhz or less such that the sound is inaudible to the human ear.

12. The method of claim 1 where the secure element transmits inaudible sound waves wirelessly using the speaker to the point of sale terminal.

13. The method of claim 12, wherein the sound wave is diffracted or bent when the sound waves travel through the opening of the speaker in the secure element.

14. The method of claim 1, wherein the secure element is configured to use power received from the point of sale terminal to transmit data to the point of sale terminal during a near field communication induction.

15. The method of claim 1, wherein the secure element uses power from a power harvesting circuitry to harvest power from ambient RF signals.

16. The method of claim 1 where the secure element is powered by an internal battery

17. The method of claim 7, wherein the internal battery in the secure element is woken up and exits sleep mode after induction which occurs when the secure element is held in proximity to a POS/POE and an API in the secure element turns the second microphone on.

18. The method of claim 1, wherein the secure element includes a screen for displaying images.

10. A method for transmitting data from a secure element physically coupled to a watch to a point of sale terminal comprising,

transmitting data from the secure element to the point of sale terminal using inaudible sound wave, wherein:

the secure element comprises a wireless transceiver, processor, memory, microphone, speaker, an Audio to Digital converter and

receiving at the secure element data from the point of sale terminal.
