Aluratek's Track Tag attaches easily to your keychain, bag, wallet, vehicle, or other personal accessories. Simply add the Track Tag to your Apple iPhone devices in the “Find My" app to track and locate your item with the Track Tag instantly, and you can play a sound on the built-in speaker via the "Find My" app. Just follow the sound and your search is over. When you've left something far behind, the “Find My" network helps track down your Track Tag by sending out a secure signal that can be detected by nearby devices in the Find My networks.
