The Low Energy extensions in Bluetooth 4.0 are some of the more interesting things to happen to the protocol in a long time, allowing wireless devices to have battery lives that extend into months. Rumors have suggested that Nokia will add Bluetooth 4.0 and LE support to its Lumia family by means of the upcoming Amber software release, and now that’s joined by talk of an accessory designed to take advantage of this new connectivity: the Treasure Tag.
According to the sources behind this rumor, the Treasure Tag is a small battery powered fob that is paired with a Lumia via NFC and attached to something you want to keep track of: maybe a ring of keys, or a bag you’re always misplacing. When you want to find the Tag, you can wake up your phone, and if the Tag is within range, an app will point you right to where it is, using one of those augmented reality displays Nokia loves so much.
It would even work the other way around, to an extent, and pressing a button on the Treasure Tag would cause the phone it’s been paired with to let out an audio alert to help you track down your handset.
Supposedly, the Treasure Tag would get six months of operation on one battery, thanks to those Bluetooth LE savings. We haven’t heard any word on pricing, but Nokia’s going to have to make this pretty cheap to attract serious interest.
