I've also seen this in a UK airport. I did not think it was a hologram. When I read the title, I was expecting something different: A pool of agents "beaming into" the busy hotspots from a central, remote location. E.g. If airport A is quieter than airport B, then the agents just beam into airport B. The agent can see the person via camera, and can tell the person to place his passport in a reader that quickly scans all pages, and sends the agent an image. To stamp the passport, the agent can tell the person place page X in slot "Y", where the agent can release the stamp remotely. Then I read about the $180k non-interactive cardboard cutouts....
