Nokia looks to be launching new accessories to take advantage of Bluetooth LE support in Windows Phone, with an image of the Nokia Treasure Tag appearing online.

As you might expect, the leaked image comes from @evleaks, who is developing a reputation as Twitter's most prolific leaker in the world of everything smartphone related.

The Nokia Treasure Tag was previously seen passing through the FCC and looks to be a Bluetooth accessory that you can attach to something, like your keys, so you can track them using your phone. It's not a new idea, with plenty of Bluetooth leashes launching previously, but combining Bluetooth LE's power efficiency with NFC's convenience makes a lot of sense.

There's no official confirmation from Nokia yet, but Nokia has previously announced that there will be a 22 October event to launch new products - perhaps the Nokia Treasure Tag will be in the mix.
