Delta airlines is investing in an RFID tracking system to keep tabs on where your luggage is.

There are a handful of beneficial features. Here are some:

* Fliers will be able to track their bags through the Delta smartphone app, getting push notifications at each step of the journey. If a bag misses its flight, passengers are also notified instantly.
* They’ll will have 1,500 special belt loaders with RFID readers built in. Those loaders stop when a bag for a different flight is accidentally placed on the belt.
* RFID shortens the time needed to find and remove a bag from a plane at the last second.
* RFID will track bags through the labyrinth of conveyor belts below terminals. If bags fall off a belt at a particular curve or get stuck at a junction, Delta will now have enough RFID readers – about 5,200 globally – to pinpoint the trouble spot and fix it.

In the future, a permanent RFID tag may be able to be purchased to install on your luggage for tracking.
