According to Nikkei, Fujitsu Software Technologies developed a device that integrates an active RFID tag and a GPS receiver. It will likely cost about 20,000 JPY (about $170) each. The GPS component of the tag first detects its location with the accuracy of 3-5m and then sends out the location data along with its unique ID to an RFID reader. It uses the 429MHz frequency band and the communication range is about 200m. These tags could be used to track cars in a large car dealer shop, etc.
