According to Digital Trends, for the next 6 months London Heathrow Airport and Emirates Airlines are testing RFID tagging to track luggage. Not just for internal airport use, the traveler will also receive text message updates as to the location of their bags. Hopefully all will bode well with Emirates Airlines and Heathrow, and the rest of the airport World will roll this technology out. It will be interesting to see how this system addresses the ‘lost luggage’ concern. No doubt this will draw some privacy concerns, though.
