They've had this for a while in immigration at least. Second time I visited (about 2003) I was greeted with a picture of my first visit through immigration there. Shown on a flat panel with a camera on top. Might just've been a tech demo though.

The existing ones are for returning citizens and PRs for arrival. The new terminal is using facial recognition for all immigration for departure as well, meaning there's no immigration officer. A swift process.
