How Tile works and is it safe to use it?

Hi there, I found Tile project on Kickstarter and I'd like to know how it actually works, I didn't quite get it from the description. Tile seems to be really useful gadget, but it would be very nice to be sure that this is safe. Many thanks in advance!

We at Jammer-Store have checked this device and we will be glad to provide you with all the necessary information. First of all you should know that it works only with iOS devices, such as: iPhone 4S and iPhone 5, iPad mini, iPad 3rd and 4th gen, iPod Touch 5th gen. You will have to download and install an app, to use that gadget. We've also reviewed that kind of gadget - you can see it here. Also, keep in mind that it only helps you to find the thing it is attached to, but it won't find it without your assistance.

Tile uses Bluetooth 4.0 standard to establish connection between the beacon and your smartphone or tablet. Bluetooth is a rather vulnerable standard, so it is hard to say that Tile is safe to use in public places. The device simply measures the distance to the beacon, using the signal strength, the stronger it is – the closer the beacon and vice versa. So, if you expect it to work like a radar of some sort – it won't, it will just measure the distance. 

Another problem you can face, using that gadget is the fact that Bluetooth has a limited range of reception, so if you'll get too far from the object – you won't find it. Any signal interference, caused by obstacles and other emitters, like Bluetooth jammers will disrupt the work of a Tile. But for a home use – it is a really interesting gadget with affordable price.

Thanks for your question, I hope, I've managed to help.
