Designed to prevent theft of small removal devices, such as Dongles, the Super-Lok Dongle-Lok is easy to use and is ideal for keeping these devices safe. Simply feed the loop through the hole in the dongle. A Super Lok cable is required to feed through the loop. A dongle (pronounced DONG-uhl) is a mechanism for ensuring that only authorized users can copy or use specific software applications, especially very expensive programs. Common mechanisms include a hardware key that plugs into a parallel or serial port on a computer and that a software application accesses for verification before continuing to run; special key diskettes accessed in a similar manner; and registration numbers that are loaded into some form of ROM (read-only memory) at the factory or during system setup.
