USB Key license
The USB key license is programmed on the USB hardware key. The USB key requires driver installation and must be plugged in to the computer to start the DICOM viewer or for a network license, in the server to handle startup request. The USB hardware key license requires extra costs which include the USB key itself, courier shipping and is available as a single license or network/floating licenses.
USB key driver installation is part of the DICOM viewer installation process but can be installed separately.
