Hereby a marking with improved security for avoiding reading errors which ensures a mandatory visual inspection of content is obtained. The transparent conductor can be in form of a polymer, an ITO and the like. These transparent conductors are used in an improved marking technique, which further improves reading security. The invention may e.g. be used in connection with medication delivery devices for self-treatment of a disease, e.g. diabetes. |
