Abstract

A wireless communication device optically receives an image and processes the optically received image to generate image data. The wireless communication device receives a Radio Frequency (RF) signal and processes the RF signal to derive an image data processing parameter. The image data processing parameter could be an encryption key, authentication code, access code, or some other parameter. The wireless communication device processes the image data and the image data processing parameter to convert the image data into a different format. The different format could be decrypted, authenticated, accessed, or some other converted form of image data.

Claims

1. A method of operating a wireless communication device comprising:

optically receiving an image into the wireless communication device and processing the optically received image to generate image data, wherein the image data comprises an instruction;

processing the instruction to determine an excitation signal;

transmitting the excitation signal;

in response to the excitation signal, receiving a Radio Frequency (RF) signal into the wireless communication device and processing the RF signal to derive an image data processing parameter; and

processing the image data and the image data processing parameter to convert the image data into a different format.

2. The method of claim 1 wherein transmitting the excitation signal comprises transmitting the excitation signal from the wireless communication device to drive transmission of the RF signal.

3. The method of claim 1 wherein the instruction directs the wireless communication device to transmit the excitation signal and wherein transmitting the excitation signal comprises transmitting the excitation signal in response to processing the instruction.

4. The method of claim 1 wherein the image data indicates an RF frequency for the RF signal and wherein receiving the RF signal comprises receiving the RF signal at the RF frequency.

5. The method of claim 1 wherein the image data is encrypted, wherein the image processing parameter comprises an encryption key, and wherein processing the image data and the image processing parameter to convert the image data into the different format comprises decrypting the encrypted image data with the encryption key.

6. The method of claim 1 wherein the image data is unauthenticated, wherein the image processing parameter comprises an authentication code, and wherein processing the image data and the image processing parameter to convert the image data into the different format comprises authenticating the image data with the authentication code.

7. The method of claim 1 wherein the image processing parameter comprises an access code, wherein processing the image data and the image processing parameter to convert the image data into the different format comprises wirelessly transmitting the image data and the access code and wirelessly receiving the image data in the different format, wherein a remote system receives the image data and the access code transmitted by the wireless communication device and transfers the image data in the different format to the wireless communication device in response to the access code.

8. The method of claim 1 wherein the image comprises RF ink that transmits the RF signal.

9. The method of claim 1 wherein the image comprises a two-dimensional bar code.

10. The method of claim 1 wherein the wireless communication device comprises a mobile Internet access device.
