Biometric wallet

To me it is a bit of an overkill, but if you have $825 USD to spare, you can get this biometric wallet from dunhill. Supposedly virtually indestructible, it opens only with touch of your fingerprint. You can also link the wallet via Bluetooth to your mobile phone which will trigger an alarm if the two are separated by more than 5 metres. Can be quite annoying if you often misplace either.

The biometric wallet exterior is built from very durable carbon fibre and can be only broken with a sledge hammer, just kidding, but it is quite impregnable. The interior features a luxurious leather credit card holder and a strong stainless steel money clip. Check it at dunhill.
