Use of mobile devices for the purpose of reading information from the packaging has already been present for some time. Today present applications that replace bar or QR code readers with a mobile camera interact with the database server successfully and transmit information about the product. This paper shows the conceptual solution for reading not only product information but also the condition of the product in terms of freshness, shelf-life and protection. The paper gives an overview of existing solutions of special inks that could be used in order to create smart labels, the algorithm for data reading through the camera of the mobile devices and mobile application. The aim is to set up a concept for the development of smart labels, from the standpoint of the materials and existing QR codes, but also to define the basis for the development of mobile application that can provide information on the state of the product in interaction with special inks.
