Each dongle of the Guardant family contains a special 4-byte number – dongle’s ID. This ID is unique. It is recorded into the dongle as a factory setting and cannot be copied or changed by anyone including the developers of Guardant. The value of the ID can be used for establishing a fixed link between the protected application and this particular dongle. Use the diagnostics utility to view the dongle’s ID, or the utility for programming the dongles called GrdUtil.exe.
