Each USB-stick is unique, and during the production process (writing data to the stick) this uniqueness is coded in a small hidden file. When the protected program is run, the code is matched against the USB-stick. The program runs only if the right USB-stick is present. There is no need for any user actions; the copy-protection is transparent.
