Nokia is looking to launch a proximity sensor accessory for Lumia Windows Phones, according to sources familiar with company plans. The Verge reports that Nokia will release a "Treasure Tag" that will combine Bluetooth 4.0 and NFC to track items of possession from a Windows Phone. The tag will pair with a smartphone through NFC and can then be attached to keys, etc. with a supplied loop strap. 

This will enable consumers to track items with a Windows Phone app and the accessory. Nokia's Treasure Tag app will offer functionality to manage the sensor and locate it when lost, making this a perfect solution for those who are prone to losing stuff. If you're not sure where you placed the item which is tied to a Treasure Tag, the Windows Phone app will display the sensor location on a map. Since this is a Nokia solution, support for LiveSight augmented reality is included.

It's also reported that by holding down a key on the device will trigger a notification on a paired handset if in range - handy if you're looking to see what phones are connected. Designed to be "always on," the Treasure Tag includes a battery that will last for approximately six months of use.

Nokia will be brining Bluetooth 4.0 support to the Lumia 520, 620 and 720, as well as the Lumia 820, 920 and Lumia 1020 families of Windows Phones. All Nokia Windows Phone 8 hardware evidently include chipsets that support Bluetooth 4.0, but the functionality has yet to be enabled.

This is just an example of what Nokia will be planning to do with the new Bluetooth 4.0 support that's being introduced in the Amber update for Lumia Windows Phones. Nokia is also believed to be planning other accessories to take full advantage of Low Energy support. With the Amber update rolling out in the coming weeks, we can expect to see the Treasure Tag and other compatible accessories launch soon.
