There's that sinking moment at the baggage carousel when you realize yours didn't make it. Better GPS and tracking tech makes it easier for baggage handlers to get suitcases back to their rightful owners. While no tech can prevent luggage from getting lost or stolen, travelers have had some success using traceable tags. Each kind on the market has limitations, though, so check details and reviews before buying. In the United States, Dynotag and Soren make Web and GPS-enabled smart luggage tags that can be customized to only display certain contact info. And if you're just trying to find your bag on the carousel, there are remote-controlled luggage locators that beep and flash when the remote is less than 60 feet away.
