It does, and feeds into the same stats database. Unfortunately I can't seem to get to caffeine.acm. I'm unsure how that works these days, since a lot of things were redesigned after I left (including retiring AFS).

When I left in 2011, there was a card reader and a touch screen, so you swiped your card, and then selected your choice on the screen. I think it may have also had a random button at one time or another. The intention was to eventually wire up the physical buttons once again to work closer to a regular soda machine.

For a while, it was wired up to twitter: https://twitter.com/acmsoda

We did have some special "admin" cards for correcting misvends, typically someone's library card or something similar.

We had the physical buttons wired up and replaced the touchscreen with a larger (non-touch) LCD panel circa late 2011. We wanted to get some LCD modules to replace the empty panels next to the buttons, but I don't know if they were ever wired up (I know we built them, but I recall there being a major blocking problem).

I'm amazed the thing kept tweeting a year after I graduated.
