GiD - The personal pre and post processor

USB memory sticks valid to register GiD

GiD licence can be attached to an USB memory stick (portable licence)

In general near all current memory sticks are valid to register GiD, only some very old devices (specially mp3 players) are unable to register GiD.

In any case the only way is check it: plug the memory stick, go to menu Help->Register GiD->USB... and see if our device appear to be selected.
