If you’ve ever lost your keys or your phone, then you know how immensely frustrating such a thing can be. Until recently, the only recourse was to hope that whatever it was that you lost would eventually turn up or that someone would find it and return it to you. Fortunately, there is technology that can help you find your lost item and even proactively prevent you from losing it in the first place. And that technology is known as low-energy RFID (a feature of Bluetooth 4.0.) Where does one get such a technology?
As it turns out, some clever manufacturers have packed this technology up in the form of tags and dongles and made them small enough to attach to your keys or anything else you might possibly lose. There’s a whole bunch of them even! They go by the names “Proximo Tracker”, “Protag Duet”, “LassoTag”, “Tile”, “Stick ‘n’ Find”, “TrackR Wallet”, and even “KeyFinder”.
And the best part is that they sell for around $30.
