I don’t check bags when I fly, but if I did … Bluebird is a Bluetooth luggage tag. Once paired, Bluebird will communicate with your phone as soon as it is in range (within 30 feet), sending a signal to the phone, and flashing brightly to get your attention. So, no standing at the carousel, instead you sit and wait (probably online via a Bluetooth connection) and when your luggage eventually rolls into range you’ll be notified. This type of thinking just warms the heart (and may even justify checking luggage!). See story at http://www.esato.com/news/article.php/id=138.
