Dunhill’s Biometric Wallet is a sleek, lightweight carbon fiber-wrapped vault that opens via a biometric swipe of your finger. The high-tech materials used to produce these wallets provide a virtually-indestructible architecture in a feather-weight form. The system can also be hooked up to your mobile phone via Bluetooth to alert you if the wallet becomes too far from you and your cell. Just be prepared to dish out $700 for it.
