Well, let’s look at the latest United Airline effort along those lines as described here (and in a USA Today article from 02/02/2009). They have taken the problem slightly differently and included the customers at the center stage by providing them with direct benefits in the form of faster check-in and assurance that their bag is tagged correctly. A clear advantage of this solution is that the tags are not changed every time and are reused and also that customers have a clear interest in having the tags correctly installed so they maximize their chances of getting their bags back in the end.
I think it is a good example of looking at an existing problem and technology with a new angle in order to find a innovative way of solving problems. RFID like other newer technologies give us the opportunity to do just that.
