A Transfer System is a system that transfers goods to remote locations via gate-jump technology.
Transport technology that uses gate-jump technology with the U.M.N. to transfer goods to remote locations.
Because KOS-MOS's weapons system includes this capability, she doesn't need to lug around oversized weapons--they can simply be transported from the storage facility as needed.
However, only goods with static data can be directly transferred. Theoretically, lifeforms with fluctuating data can be transferred directly, but it is more or less impossible given the major mental and physical difficulties that can arise.
To transfer living things, one must use a spaceship equipped with the appropriate system.
