eTag, on the other hand, is a "high-tech luggage label" that affixes to the outside of the bag and replaces the airline's routing sticker. Because it's electronic (and also syncs with your phone), you don't need to relabel the bag for each trip -- your flight details are updated automatically. Even better, once you own an eTag, you don't need to check-in your suitcase! Nope, you simply deposit it at the airport's fast bag drop and go grab a cup of coffee or beer.
While the devices will be sold separately, super-anal passengers can -- like wearing a belt and suspenders -- use the eTag and eTrack together. And uber security-conscious fliers can even use the devices with Samsonite's Track and Trace suitcase, ensuring nobody is walking away with their favorite business casual sweatsedo.
