All of our baggage tags have RF chips but the system to use them has not been installed. The idea is to track each and every bag from check-in to destination. It will be good when it happens but will this information be shared with passengers? Flying passengers when they know their bags or not onboard might be difficult.
There was also a plan to check passengers in the same way but smartphones got in the way. You can read a boarding pass with an RF chip quite easily but you can't track a phone that is turned off.
