Abstract
A method for reading and using partial data from a portable data carrier includes reading data from a portable data carrier, determining if any data is missing, and if any data is missing, restructuring the data for use, such as for running an audio decoder and expander. A method for writing data to a portable data carrier having limited capacity includes receiving a data file and optimizing at least one encoding parameter to fit at least a portion of the data file into the portable data carrier.

16. A system configured to read and use a partial set of data from a 2D bar code symbol comprising:
-
an image capture module configured to capture at an image corresponding to at least a portion of a 2D matrix symbol; a processor configured to determine if at least one segment of data is missing in audio data read from the 2D matrix symbol, and if at least one segment of data is missing, restructure the data for optimum playback. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)

29. A method for processing data from a portable data carrier comprising:
-
interrogating the portable data carrier; receiving a portion less than the full amount of the data in the portable data carrier; and processing the received portion of data to put the data into temporal registration; wherein the data corresponds to-an audio file or a video file.

30. A method for processing data from a portable data carrier comprising:
-
interrogating the portable data carrier; receiving a portion less than the full amount of the data in the portable data carrier; and processing the received portion of data to put the data into temporal registration; wherein putting the less than the full amount of the data into temporal registration includes inserting the portion less than the full amount of the data and time corresponding to missing data into an audio file or a video file.

31. A method for processing data from a portable data carrier comprising:
-
interrogating the portable data carrier; receiving a portion less than the full amount of the data in the portable data carrier; and processing the received portion of data to put the data into temporal registration; wherein putting the less than the full amount of the data into temporal registration includes inserting one or more pad characters between received characters.
