Abstract

Techniques for connecting using NFC communications are provided. Specifically, methods are presented, that when taken alone or together, provide a device or group of devices with a secure way of transferring data from a wireless device to a reader. The present disclosure includes a method that provides a wireless device with network connectivity options that enable a more secure means for using NFC communications for completing a secure transaction using a secondary code.

First claim

The invention claimed is:

1. A communication device, comprising:
a memory;
a transceiver, the transceiver configured to:
transmit a radio frequency (RF) signal indicating the presence of the communication device and the availability of the communication device to communicate with a wireless device;

a processor, the processor configured to:
process a secure code, wherein processing the secure code includes sharing the secure code with an unlock engine in the communication device and the wireless device over an augmented optical communication channel;

the transceiver further configured to:
receive a short range signal over a primary RF channel with secure information from the wireless device; and

the processor further configure to:
unlock the secure information received over the primary RF channel using the secure code and the unlock engine.

2. The communication device of claim 1 , wherein processing the secure code further includes using a key pair generator to generate a one-time key and wherein the one-time key is used to create a secure code.

3. The communication device of claim 2 , wherein the secure code is displayed to the wireless device using the augmented optical communication channel.

4. The communication device of claim 1 , wherein processing the secure code further includes receiving the secure code over the augmented optical communication channel from the wireless device.

5. The communication device of claim 2 , wherein the one-time key can be generated by the key pair generator in the communication device and the wireless device.

6. The communication device of claim 1 , wherein the secure code is one or more of a QR code, an IR code, a photograph, a digital certificate, or a fingerprint.

7. The communication device of claim 1 , wherein in receiving the short range signal further includes initiating a timer, wherein if the timer expires prior to receipt of the short range signal, the communication ends, and wherein the short range signal includes an NFC signal.

8. The communication device of claim 1 , wherein the secure information received is hardened by the secure code, wherein the secure information is hardened when encrypted with the secure code, and wherein the secure information includes transactional data.

9. The communication device of claim 1 , wherein the secure code is used as a key to unlock the secure information received over the primary RF channel, and wherein the unlock engine ensures the key compliments the secured information received before processing a transaction.

10. A method comprising:
transmitting, by a transceiver, a radio frequency (RF) signal indicating the presence of a communication device and the availability of the communication device to communicate with a wireless device;
processing, by a processor, a secure code, wherein processing the secure code includes sharing the secure code with an unlock engine in the communication device and the wireless device over an augmented optical communication channel;
receiving, by the transceiver, a short range signal over a primary RF channel with secure information from the wireless device; and
unlocking, by the processor, the secure information received over the primary RF channel using the secure code and the unlock engine.

11. The method of claim 10 , wherein processing the secure code further includes using a key pair generator to generate a one-time key, wherein the one-time key is used to create a secure code, and wherein the secure code is displayed to the wireless device using the augmented optical communication channel, and wherein processing the secure code further includes receiving the secure code over the augmented optical communication channel from the wireless device.

12. The method of claim 10 , wherein in receiving the short range signal further includes initiating a timer, wherein if the timer expires prior to receipt of the short range signal, the communication ends, and wherein the short range signal includes an NFC signal.

13. The method of claim 10 , wherein the secure information received is hardened by the secure code, wherein the secure information is hardened when encrypted with the secure code, and wherein the secure information includes transactional data.

14. The method of claim 10 , wherein the secure code is used as a key to unlock the secure information received over the primary RF channel, and wherein the unlock engine ensures the key compliments the secured information received before processing a transaction.

15. A non-transitory computer readable medium having instructions thereon that when executed by at least one processor of a communication device perform a method comprising:
transmitting, by a transceiver, a radio frequency (RF) signal indicating the presence of the communication device and the availability of the communication device to communicate with a wireless device;
processing, by a processor, a secure code, wherein processing the secure code includes sharing the secure code with an unlock engine in the communication device and the wireless device over an augmented optical communication channel;
receiving, by the transceiver, a short range signal over a primary RF channel with secure information from the wireless device; and
unlocking, by the processor, the secure information received over the primary RF channel using the secure code and the unlock engine.

16. The non-transitory medium of claim 15 , wherein processing the secure code further includes using a key pair generator to generate a one-time key, wherein the one-time key is used to create a secure code and wherein the secure code is displayed to the wireless device using the augmented optical communication channel.

17. The non-transitory medium of claim 15 , wherein processing the secure code further includes receiving the secure code over the augmented optical communication channel from the wireless device.

18. The non-transitory medium of claim 16 , wherein the secure information received is hardened by the secure code, wherein the secure information is hardened when encrypted with the secure code, and wherein the secure information includes transactional data.

19. The non-transitory medium of claim 16 , wherein the secure code is used as a key to unlock the secure information received over the primary RF channel, and wherein the unlock engine ensures the key compliments the secured information received before processing a transaction.

20. A wireless device, comprising:
a memory;
a transceiver, the transceiver configured to:
receive a radio frequency (RF) signal indicating the presence of a communication device and the availability of the communication device to communicate with the wireless device;

a processor, the processor configured to:
process a secure code, wherein processing the secure code includes sharing the secure code with an unlock engine in the communication device and the wireless device over an augmented optical communication channel;

the transceiver further configured to:
transmit a short range signal over a primary RF channel with secure information from the wireless device; and

the processor further configure to:
unlock the secure information transmitted over the primary RF channel using the secure code and the unlock engine in the communication device.

21. The wireless device of claim 20 , wherein processing the secure code includes reading the secure code displayed by the communication device using an augmented optical communication channel, and wherein t
