SmartWallit: Smartphone alerts you when your wallet gets lost
Now this is what we call a smart idea: the SmartWallit is an anti-lost accessory that connects with any smartphone with Bluetooth 4.0 or BLE (think iPhone 4s, iPhone 5 or Android). All you have to do is strap on the super-thin anti-lost device to any object you like — such as your wallet — and when it strays beyond the preset threshold (the default distance-warning is 10 meters or 30 feet) of your smartphone, your phone will alert you by ringing and vibrating to signal that you have wandered off and left your belonging behind.
It also comes in handy when you know you have been scatterbrained: you can use the app on your smartphone to make the anti-lost device ring at a volume of over 85dB, as well as view the distance between your phone and the object. Now, now, all we have is one question: what happens if we want to use it on our phone?
