The next time you lose something, you won’t be at a loss. At least, not if you’re using FOUND IN TOWN, a new free online service that reunites missing items and their owners. The first step is to register at FoundinTown.com; you’ll then receive a set of tags (with a unique ID number) that you affix to your belongings: luggage, laptop, phones, wallet — you name it. Should a tagged item go missing and a good Samaritan stumbles upon it, he or she just follows the instructions on the tag and the system automatically sends you an anonymous email alerting you that the item has been found.
