I’d need a gadget like this to have all my important items safe near me. It’s called Button TrackR are is a project available for crowdfunding at indiegogo.
This is a tracking device at the size of a quarter, which you can place on almost anything and pair it with an application to keep track of your iPad, smartphone, pet, keys, and others, within the supported range of 100 feet. It’s a great thing that you can use the app to track up to 10 devices simultaneously if you have 10 Button TrackRs.
Another cool feature of this gadget is that other users of this app can help you locate your lost items because when they pass nearby them, you’ll receive a push notification with the GPS coordinates. This happens in addition to getting notification whenever you leave a specific area forgetting to take the protected item with you.
Button TrackR works based on Bluetooth, powers from a coin cell battery, and measures 25 x 4 mm which means it wouldn’t look good on a small item such as keys or smartphone, that’s why I’d prefer it smaller, like about half the actual size.
