Radio Frequency Identification (RFID) is a wireless technology that is emerging in consumer products as a method for input and interaction. Although RFID is relatively well known from a technical perspective, the methods and for designing with RFID are less well understood, particularly the tangible and physical aspects of RFID form. Using a practice-driven design approach we explore the possibilities for richer design of RFID objects in everyday contexts. Through sketching, making and form-explorations we build a visual and physical design vocabulary for RFID forms. This includes properties such as direction, balance, ergonomics and geometry that are communicated through design-focused language and visualisations.
