Abstract
Decoding or encoding information in a two-dimensional barcode, the barcode comprising an orientation pattern and a payload data pattern both being compiled of first and second type elements. The decoding or encoding involves a two-dimensional transformation applying at least to the payload data pattern in connection with second information that forms together with first information the information encoded in the two-dimensional barcode.
