Device built into the upper surface of the hand near the knuckles that normally is hidden from view. When active connectors shoot out of the device just behind the knuckles, going through skin connecting with electrical or computer circuitry. Once retracted skin grows back in around 30 to 60 seconds.
Operation
Once connected to a circuit board the jacks produce and spread fine nano-fibers over the circuits to seek out any computer chips to interface with. When retracted the jacks leave the nano-fibers behind.
