Co-developing services utilizing printed functionality

2D bar codes have been available for almost 30 years, but during the recent years their popularity has increased. The use of functional printing methods in code printing enables that novel digital services are created for the consumers and other stakeholders. Functional inks make it possible for parts of the 2D code to disappear, to appear, or to change colour e.g. after certain time or at certain temperature. These changes in codes enable changing the information content achievable through reading the codes. The content behind the codes should offer added value for the users, as consumers are not willing to read the codes just for getting a link to a web page. Novel services utilising functional printed codes, can take into account different types of user and context related data, such as user profile and GPS location of the smartphone. These context-aware features will futher improve the value and quality of the services provided. In this study we tested consumer attitude towards services in which functional 2D cods were used and demonstrated their printing in pilot scale.
