A good use for RFID tags

Delta Airlines has announced plans to use RFIDs (Radio Frequency ID) to track and manage luggage. Finally--a great use for RFIDs that has no privacy problems (unlike proposals to embed them in clothing so that we can be tracked 24 hours a day by the Gap). An RFID on a luggage tag will allow the airline to be able to tell where a piece of luggage is virtually in real time. If Delta does its homework on the staffing and management side, the airline should be able to dramatically cut the cost of dealing with lost luggage and make customers much happier at the same time--a win-win for new technology.
