Speaking of the Family Travel Association, they have partnered with ReboundTAG, a UK company which produced the first microchip luggage tag that works in all airports worldwide. The ReboundTAG system is integrated with global baggage handling systems; so that it works in all airports worldwide.  The tag incorporates all relevant airport technologies in one tag!  Members are updated by SMS and email when their bag is found.  It even uses GPS within the finder’s phone to provide you with the exact location of your bag.
