At AT and T researchers have developed a "smart luggage" tracker that would help travellers find their bags.
The tracking device, which fits inside or is attached to luggage, pinpoints the location of a bag in real time, PC World reported.
Users could track the movement of their luggage through software on a mobile device, David Marten, principal hardware designer at the company's machine-to-machine foundry, during the AT and T Innovation Showcase in New York said.
The application could also send text messages at specific intervals for when a bag lands and the tracking device could also light up a bag at lost-and-found or on a carousel. The tracker in the bag could work internationally by connecting to other 3G-compatible networks.
