Noticed this new addition to the entrance of the Mackay lounge this evening - a self-admit scan your own card entry terminal. I also took a photo of the whole machine, but it didn't turn out, unfortunately. This is just the screen.
Physically, it resembles a Qantas RFID check-in pole, and once you swipe your card, you get prompted to touch the screen to indicate the number of guests you're bringing in (0, 1, 2, 3 for my Plat card).

Any sightings at any other lounge?
