A $600 carbon fiber and Kevlar wallet ($299 for fiberglass version) might seem expensive, but if you frequently forget your wallet or cellphone, it could be the best money you ever spent. It's loaded up with Bluetooth and biometrics.
Here is how it works: the wallet connects to your cellphone via Bluetooth. When the two objects are separated by more than 15-30 feet, the wallet will sound an alarm. So, in reality, it is really protecting you from losing two important items. The wallet also features a biometric fingerprint reader that will only open for its owner. On the other hand, if you leave both your cellphone and wallet behind, you are still screwed. Probably even more so since the wallet was so dammed expensive. The wallets are available for pre-order now in several colors, with shipments starting on December 11th. [iwallet via Gear Diary via OhGizmo via DVICE]
