Nowadays, you can track the location of belongings such as wallets, bikes and bags with small GPS trackers, and the coin-sized TrackerPad is perhaps the smallest of the lot.
There are already some pretty tiny tracking devices on the market, such as the TrackR Bravo and the Tile. At only 10 x 10 x 3.8 mm (0.39 x 0.39 x 0.15 in), though, the TrackerPad is roughly the same size as a British 10 pence piece or a US quarter, making it significantly smaller than both of those options.
Whereas the casings of the TrackR Bravo and the Tile are made of hard materials, the workings of the TrackerPad are enclosed within a soft, flexible casing. It weighs just 1.6 g (0.05 oz) and is attached to objects using its adhesive rear.
The TrackerPad has a built-in prepaid SIM that communicates with the TrackerPad server and the server, in turn, relays info to an accompanying TrackerPad app on the user's smartphone (platforms yet to be confirmed).
Pads are paired with the app by scanning the unique QR code on the front. Once paired, the pads can then be named for easy reference. For example, you might name them after the object to which they are attached.
Using the app, it is then possible to select a TrackerPad pad by its name and view its location on a map. Automated location reports can be set up at intervals of the user's choosing and geo-fencing can be set up so that the user receives a notification if the Pad exits a defined boundary.
TrackerPads have a battery life of around seven days depending on how often their location is reported. The pads are charged using a wireless charger. Once a Pad has been placed on top of the charger, the user will receive a notification via the app to say that charging has begun.
The company says the devices are waterproof and can be used repeatedly. If a one loses its stickiness, the adhesive surface needs only be run the under water and to "reactivate" it.
A Kickstarter crowdfunding campaign is underway for the TrackerPad. A pledge of £30 (US$46) put you in line for two TrackerPads, a wireless charging bay and codes with which to download the accompanying smartphone app. Delivery is expected in December 2015 if the campaign succeeds.
The Kickstarter pitch for the TrackerPad is below.
UPDATE (Aug. 6/15): TrackerPad has now moved its crowdfunding campaign to Indiegogo.
