Abstract:
1. Method for decoding data that is encoded on a medium in a two-dimensional arrangement of code symbol marks, wherein the two-dimensional arrangement comprises a data range, within which the position of each code symbol mark, is linkable to a defined piece of data, wherein the two-dimensional arrangement comprises orientation symbol marks that define the data range and wherein the two-dimensional arrangement of code symbol marks and orientation symbol marks are read by way of a code reader, wherein the orientation symbol marks are disposed in several rows and several columns, comprising adjusting a grid of row centerlines and column centerlines to the read orientation symbol marks by determining the step width for the rows and the step width for the columns and, after determining the step width for the rows and the step width for the columns, assigning read code symbol marks to one respective point of intersection of the adjusted grid, the point of intersection being linkable to a defined piece of data.
