If you're really good at losing your keys, your wallet, or even your phone, then you may want to invest in something like this.
I'm Jessica Dolcourt for Cnet and this is the Nokia Treasure Tag.
Now this is simply a bluetooth tracking device that uses blue tooth low energy and NFC preparing if your phone has that, but you don't need NFC on your device to use it.
In fact, you don't even need a Window's phone or a Lumia.
It also works for the Android or IOS.
So, it's small and squared.
There is an optional loop that you can take off.
It's got a button in the center and you would press this to find your phone.
On an other hand, your phone has an app that controls the device.
So, if you're disconnected for example,.
You can see where we were last on a map.
You can also press a button in the app to find the device.
So, it works both ways.
If you know where your key is, you can find your phone.
If you know where your phone is, you can find whatever else this is attached to.
Although it's pretty small, I found it was actually a little bit big and chunky when I attached it to my keys.
...Can't fit it in your wallet, so Nokia does have a smaller size, the treasure tag mini.
That's half the width.
I personally would hold out for that one.
It's a little bit smaller and it's going to fit into your life a lot better.
