TrackR bravo is the thinnest item-tracking device ever is the latest entrant in a crowded market led by the already-available Elgato smartkey, but its slim elegance means it’s likely to turn a few heads down the electronics shop.

Allegedly created through five years of product development the device works with iOS and Android devices to let you track your phone, wallet, whatever you have your TrackR bravo attached to. Like many devices of its type this uses Bluetooth to help you find it and is about the size of a coin.

The company also claims to have implemented a form of crowd-based Bluetooth GPS object finding technology, but given this was a feature promised by an earlier Kickstarter project, which later removed claims to the feature, it is open to question if this will be part of what you get. However, there’s clearly a big market in Bluetooth devices, judging from the massive over funding that’s already happened to this not yet closed project.
