Nokia today announced Treasure Tag, an NFC and Bluetooth powered fob that will alert users when their phone is too far away from their keys and vice versa. The device, which Nokia says is about the size of a matchbook, can be attached to a keychain (or other item the owner wants to keep close by) and then paired with a Lumia smartphone through a dedicated app. First-time users will automatically be prompted to download the app when they first pair their phone to the Treasure Tag with NFC. When the user moves one device too far away from the other, they'll both emit an alarm. Devices or tags that are lost can be located via HERE Maps. Lumia phones can support up to four tags, each of which can be identified with its own on-screen icon. Nokia said separate apps will soon be available for Android and iOS devices, as well. Nokia Treasure Tag costs $30 and will be available globally in April.
