Know how many bags get lost at airports? Last year, the number hit a staggering 34 million globally, according to numbers from international transport association IATA.
This cost the aviation industry $3.6 billion. One way to reduce the amount of mishandled luggage could be to switch from today's widespread bar-code tagging system to more sensitive radio frequency identification (RFID) tags. The IATA estimates that $200 million could be saved each year by such a swap at the world's top 80 airports.
