Star Wars - Age of Rebellion
Small, complex devices about the size of a human hand, holo-messengers are used when a personal touch is needed in the sending of a message. Equipped with a small holographic display emitter, these devices can be used either to send a one-time recorded message or to act as a receive-and-display device for a holographic transmission. When used, the messenger projects its hologram either directly over the user’s hand or anywhere he wishes (up to a meter away). Easily concealed and transported, holo-messengers are often used by various Rebel cells to send and receive secret messages.
