A direct stimulus electrode about the size of a dime. A powerful nanocellular receiver, it comes with replaceable two-sided stick-ons. You just stick the V-trode to your right or left temple and it transmits optical, auditory and tactile signals out of Virtuality. It's not as good as a cyberdeck (you can't transmit anything into V-space), but it allows you to see and hear into the alternat electronic reality that is the main information source in 2027.
