Pretty clever little idea here. Put a credit-card-sized device in your wallet. It connects to your phone via Bluetooth. You can then be alerted when you separate from your wallet and/or you can tell your wallet to beep so you can find it. It also takes a GPS snapshot of the point of separation so you can go back to the place where you left it.
Bad news: this is one of those fundraiser/kickstarter products and these fools are trying to raise a quarter million dollars. A quarter million, guys? You’re telling me you couldn’t do it for 30K? 50K? 150K? I think they’re a little overhyped on their idea here. Plus, what happens if someone steals the wallet? You have a GPS snapshot of where it was stolen, but then the Bluetooth is out of range so you’re shit out of luck.
