I got a photo of the new Costco terminals at the Poway, CA location the other day:



As previously mentioned, it still worked as expected. The UI isn't any different from the MX915s either.

I also noticed that my local Circle K remodeled since I was last in there. They seem to have some sort of self-checkout thing now where you put your items on top of a metal plate and a camera determines what you're buying (but the cashier rang up my items at the manned counter before the person in front of me could finish with the self-checkout, so I couldn't test this). Circle K does turn on contactless automatically on the first item scan now, though, so no more having to rely on cashier training.
