Some years ago a hacker called 'Melvin' commissioned designer Jeni Mattson to come up with a business card that would open doors for him. She made him a metal business card with fully functioning lock picking tools. The card can be easily dismantled. Each individual tool can be popped out and detached and cleverly used as a lock-picking kit.
Jeni then made a modified version for legendary hacker Kevin Mitnick, shown above. Mitnick's card was tested as a lock-picking kit after being handed out at at a conference in 2007.
