Assettag, an edge device of Asset Management System, was produced and licensed by Borda Technology. As Formeta Design, we involved the design process of both hardware and software of the product. After recent developments in Industry 4.0, IoT devices converted into more reasonable systems which led to the emergence of a new design field called ‘Design for IoT. While making a design Asset Tag, the most essential design criteria we met is customizing. So we used membran for the top part of the product due to changing customer requests over time. The company can just change the membrane of the product to customize it for their clients. To provide these flexible usage fields, the exterior form of the product was being chosen as simple form which allows the company to detect the removal of the product and assemble on every type of the product easily.
