The SmartWallet has some pretty cool tech in disguise. It's made of high quality leather and has a built in gps tracker with bluetooth LE. It doesn't end there though, it's not only a wallet you can keep track of but also has a built in 1000mAh battery to charge your phone. No need to carry around a heavy battery wherever you go. You will most likely have your wallet so chances are you won't forget to bring it along. This is currently a kickstarter project so they need help funding this to become a reality.
