We present a process for the development of an RFID textile, and have developed a map making system to support highly accurate position detection. Massively distributed RFIDs have the potential for location aware applications however time and cost are high for the deployment of the RFID tags, and correlation of the physical coordinates with each ID for making a map. We developed an RFID woven textile and a customized textile inspection machine with an automatic map making function. These developments have the potential to extend location aware systems with massively distributed tags. We examine the feasibility of a tracking system with RFID textile by using 19-meter coated textile as a carpet to the laboratory room and corridor. The system was calibrated in 38 mins and achieved a 10cm resolution.
