The Japanese Ministry of Internal Affairs and Communication is developing a system that will allow information to be gathered about disaster areas with the help of RFID. The system would distribute RFID tags from the sky upon the disaster area and allow for all kinds of information to be gathered wirelessly. Most importantly, the RFID tags would include heat and vibration sensors to aid in finding survivors. It's estimated that 10,000 tags would be required to cover the area the size of a large airport.
