Abstract
A data matrix code arrangement, and a method for making the same are disclosed. The data matrix code arrangement includes a fix data matrix code including a static pattern forming a first readable Data Matrix code, and an electrochemically switchable organic electrochromic display comprising pixel element including a controller arranged for enabling an application of a predetermined potential difference between an electrochromic layer and a counter electrode layer of the pixel element. The application of a potential difference initiates and maintains a colour switch of the predetermined ones of the pixel elements. The fix Data Matrix code and the display are aligned such that the static pattern of the first Data Matrix code and the predetermined ones of the pixel elements, when switched, forms a second readable Data Matrix code, which is different from the first readable Data Matrix code.
