Abstract
The invention relates to a 2D barcode comprising barcode elements, made up of elementary 2D color modules and of which encoded data are split into a plurality of 2D data blocks made of chunks, each element including a 2D alignment pattern AP of which modules have colors representative of a color palette, a configurable error-correcting code and a locator including an orientation pattern and encoded locator data indicating a size of said barcode element BE, a size of said element, a size of the data blocks DBs of said barcode element, the number of colors of the corresponding color palette, and a level of error correction of the error-correcting code.
