The Wireless PC Lock system is separated into two parts. First part is an USB Stick like receiver, as it's used for wireless mice
Second part is a transmitter for put onto the users key ring. It's possible to activate and deactivate the transmitter by using a button. The current state is displayed by a small LED behind the red button pad.
The GUI allows easy hardware setup.
After finishing the configuration process the system detects if the registered user is around by scanning for the transmitter. As soon as the user (together with the sender) is moving away, the system gets locked and the specified picture will be displayed.
In the case the sender got lost or the battery ran out of power, it's possible to unlock the system by using a 64 character password.
