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 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 products in everyday contexts. Through sketching, making and formexplorations 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 designfocused language and visualisations. Keywords RFID, interaction design, industrial design, tangible interaction, applied design.
