I put the luggage tag on my main piece of check luggage for identification in case of a lost-luggage situation. I put the smaller dongle (meant for a key-chain) on my main carry-on luggage for easy use at kiosks for check-in. I used a luggage tag strap from a luggage tag i got as a giveaway at a trade show. Works very well and is always with me (on my carry-on bag) when needed for check-in (while my keys are usually inside my carry-on bag) and I don't have to dig in my wallet for my card.
