Smart trackers: the technology that helps find lost items from your phone
Small electronic devices, shaped as keychains or thin cards, allow users to locate keys, wallets or luggage from their phone. Most use Bluetooth to detect nearby objects and trigger a sound or check the last recorded location; some rely on tracking networks of nearby phones to find them at a distance. More advanced models include ultra-wideband (UWB) for greater precision and NFC to share contact details. They run for months on a battery.
