There’s a compulsive activity I do almost everytime I leave somewhere, where I pat my front pockets for my keys, wallet, and phone, and don’t proceed until all three are accounted for. It’s a common impulse used to make sure your most necessary items are on you, but is far from infallible. For instance, sometimes you are running especially late, or are just hammered drunk, and don’t remember to take the usual precautions.

There’s been a variety of tracking devices over the years that help you keep tabs of your valuables in situations like that, but I’ve never considered one until the SmartWallit.

The SmartWallit is a small device that you slide into your wallet, and link to your phone via Bluetooth and an app. From there, if you leave your phone behind, the device in your wallet will beep as a notification. Similarly, if you snag your phone, but forget the wallet, the phone will beep, and even provide an approximate proximity to the wallet. While there is a keychain option for the device to keep the “band together” so to speak, there’s no way for it to notify you you’ve left them all, because, as in all things, at a certain point, you’re just screwed.

The SmartWallit isn’t just a high tech game of marco polo between the necessities, though, as there are additional app features. The most intriguing of which has to be the one that reads sensors from the device to know when you opened your wallet last to make a payment, and keeps a loose record of it that will show you the time and exact location it was used, meaning you’ll never forget where that twenty went to again. You can even import more advanced financial features to keep closer tabs on your active spending habits.

Looking for just under $7,000 to finish its Kickstarter campaign, the SmartWallit isn’t the first of its kind, but is among the least invasive, and most versatile, of the tracking devices I’ve seen yet. Plus you can never really have enough gadgets that help you never have to know the horror of replacing the contents of your wallet.
