Does precedent talk about transferring mass of electrons? Otherwise the transferred energy also has mass, via mass-energy equivalence.

This on the other hand is on a bit more tenuous grounds. In theory you don't actually have to move energy (and thus mass) around to move information if you use physically reversible operations. But all practical computers use irreversible operations, which means information is sent by expending some energy, this is obvious in sending photons down a fiber or radio waves being able to power a lightbulb.
