1. A method of reading and decoding scrambled and encoded two-dimensional data represented on a sheet of media as a dot matrix, the method comprising the steps of detecting a data area on the sheet of media by detecting targets on the sheet of media;
- detecting a bit pattern represented by the dot matrix and writing the bit pattern to generate a byte pattern;
descrambling the byte pattern to generate coded data; and
decoding the data.

Abstract
A method of reading and decoding scrambled and encoded two-dimensional data represented on a sheet of media as a dot matrix includes the step of detecting a data area on the sheet of media by detecting targets on the sheet of media. A bit pattern represented by the dot matrix is detected and written to generate a byte pattern. The byte pattern is descrambled to generate coded data and the data is decoded.
