Systems, methods, and computer-readable storage media are provided for acquiring field device data (e.g., imaging data such as barcode readings), extracting patterns from the field device data, and formatting the extracted patterns—all directly from field devices (e.g., barcode readers) embedded with these capabilities. The information conveyed by the patterns extracted at the devices embedded with these capabilities may be synthesized and shown in a graphical way to end-users, for instance, by exploiting IoT middleware platform services available at end-user side. Accordingly, systems, methods and computer-readable storage media in accordance with embodiments hereof further provide a customized visualization (e.g., a widget) aimed to make the formatted patterns available in an easy, intuitive and effective way.
